Abscisic acid (ABA) is a key plant growth and stress hormone involved in many biological processes. It has been shown to be involved in Reactive Oxygen Species (ROS) generation. Class-III Peroxidases (PODs) are known to maintain oxidative stress induced-ROS at sub-lethal levels in plants under abiotic stress conditions, but, studies documenting how ABA regulates boiling stable class-III PODs are still a matter of conjuncture. In this study, the ABA-induced changes on ROS and ROS scavenging class III boiling stable POD were studied in the embryos of different cultivars of wheat. Simultaneous analysis of ROS contents, activities of ROS-scavenging class- III boiling stable POD enzymes gave an integrative view of physiological state and detoxifying potential under conditions of sensitivity and tolerance. Indices of oxidative stress viz., superoxide radical and H2O2 content increased under ABA treatment in a genotype dependent manner. It was observed that cultivars :PBW 550, HD 2967 and PBW 621 have more efficient mechanism to scavenge ROS species as shown by increase in BsPOD activity accompanied by enhanced expression of boiling stable POD isoenzymes. Based on results it can be inferred that embryos of cvs. PBW 550, HD 2967 and PBW 621 have more capacity to perform biological antioxidative reactions to combat ABA-induced oxidative stress.

Ananus comosus, has demonstrated a wide variety of biological activities which make it a good plant source for the treatment of many oxidative stress mediated diseases. The present study was aimed to evaluate therapeutic potential by assaying the activities of liver marker and lysosomal enzymes in 7, 12 dimethylbenz(?)anthracene induced mammary cancer bearing rats. Animals were divided into five groups of six numbers each. Group 1 served as control, group 2 induced mammary carcinogenesis, group 3 and 4 were treated with plant extract and tamoxifen and group 5 served as animals treated with plant extract alone. All the animals were sacrificed after 30 days treatment, serum and mammary tissue are used for the analysis of liver marker and lysosomal marker enzymes using standard protocols. The rats were induced with mammary cancer by DMBA showed altered the levels of liver markers and lysosomal marker enzymes in serum and mammary tissue. On the other hand, oral administrations of ethanolic extract of Ananus comosus peel and standard drug tamoxifen to mammary cancer bearing rats for 30 days, those levels were brought back to near normal. The histology of mammary tissues inevitably supports the biochemical alterations and this was attributed due to the interaction of Ananus comosus peel through the induction or inhibition of metabolism and also the modulating property in the marker and lysosomal enzymes.

Plants for thought
Virmani, Mohamed Ashraf

The title may be misleading in suggesting that plants think, even though this is an interesting question. The argument here is how plants have evolved either by accident or by some ‘natural’ intelligence to exert effects on our thoughts.

The purpose of this study was to investigate tetrahydropalmatine (THP), a major compound in Corydalis yanhusuo WT Wang (Family: Papaveraceae) and its effects on PTSD induced neurobehavior in the rodent model. The aims were to determine the effects of THP on anxiety, locomotion, and memory. A prospective experimental between groups design was used. Eighty rats were randomly divided into two groups, non-stressed and stressed. They were then randomly subdivided into four groups: control, THP, midazolam, or THP and midazolam. The behavioral component was evaluated using the elevated plus maze (EPM) and Morris water maze (MWM) in a restraint/shock stress model. Data analysis was performed using a two-tailed Multivariate Analysis of Variance (MANOVA) and LSD post-hoc test. There were significant differences in anxiety between the groups (P<0.05). The PTSD stressed rat groups had significantly reduced time on the open arms of the EPM demonstrating significant increased anxiety compared to the control nonstressed groups. Data pertaining to the MWM did not demonstrate statistical significance. While a one-time dose of THP was insufficient in providing a significant decrease in anxiety, a multi-dose regimen may yield more effective results. Future experiments should evaluate a multi-dose or prophylactic regimen.

The effects of mutation induction through the use of a chemical mutagen as a method of improving few agronomic traits in sesame (Sesamum indicum L.) were investigated. Healthy and dry seeds of sesame varieties (Abasena and Kelafo 74) were treated with hydroxylamine hydrochloride (HA) at six different concentrations (0.01, 0.02, 0.03, 0.04, 0.05 % (w/v) and control) with the aim of improving the growth and yield parameters of the plant. Bioassay studies showed highly significant difference in germination percentage of the two varieties under the treatment of the mutagen compared to the control. The results obtained from the quantitative parameters also revealed highly significant increase (P=0.01) in the plant heights, number of seeds/pod, number of capsules/plant, internode length and capsule length with decrease in the concentration of the mutagen. In addition, days to maturity have shown a negative mean shift in all the treatments and days to flowering showed a significant positive mean shift only at 0.02% concentration of HA. The chemical mutagen was therefore found to improve the quantitative traits associated with growth and yield of sesame. The induced variation can be exploited in the evolution of new varieties of sesame with improved agronomic traits.

Drought is one of the main environmental factors affecting growth and yield of sorghum in arid and semi-arid areas of the world. In vitro selection of Sorghum bicolor for drought tolerance was undertaken by the use of somaclonal variation. The experiment was carried out with a collection of sixteen sorghum genotypes and tested in a completely randomized design. Data were recorded at five different PEG 6000 (polyethylene glycol) levels (0, 0.5, 1.0, 1.5, 2.0% (w/v) treatments)) on coleoptile length (CL), root length (RL), shoot dry weight (SDW), root dry weight (RDW), root number (RN) and statistically analyzed for significant differences. Significant differences were observed among the genotypes, treatments and their interactions for the evaluated plant traits suggesting a great amount of variability for drought tolerance in sorghum. In general, embryogenic callus induction and plantlet regeneration was found to be indirectly proportional to increased PEG concentrations. By taking into consideration all the measured traits, Mann Whitney rank sum test revealed that 76T1#23 and Teshale followed by Gambella-1107 and Melkam showed better drought stress tolerance while Chelenko appeared to be drought sensitive.

Cervical cancer is a malignant neoplasm and is the second commonest cancer in women worldwide. Despite the availability of various treatment modalities, the 5-year survival remains poor. Therefore, it is absolutely necessary to explore drugs capable of preventing and treating cervical cancer. Plant-derived natural products are widely used as adjunct to chemotherapy for this type of cancer. Our study aims to investigate the effects of acetylshikonin, an acetyl derivative, isolated from a Chinese medicinal herb Lithospermum erythrorhizon Sieb. et Zucc., a folk medicine with a long history of safe use for clinically treating cervical cancer in China. MTT assay was used to determine the in vitro anticancer effects of acetylshikonin on human cervical cancer Siha cells. The expression of caspase-3 and -8 proteins were determined. Flow cytometry and quantitative RT-PCR were performed to detect the expression level of Siha cells associated markers and regulatory genes. In Siha cell lines, acetylshikonin inhibited cell growth in a dose-dependent manner. The preferential expression of Siha cells related marker, regulatory genes were also highlighted. It arrested the cell cycle by blocking transition from S phase to G2/M phase and induced apoptosis of Siha cell through activating caspase-3 and caspase-8. In the current study, acetylshikonin can be taken as a promising natural lead for cervical cancer.

Cancer is the main cause of death worldwide. Chemotherapeutic agents used for disease treatments have shown limited antitumor activity, with a high recurrence rate. It has prompted the research efforts to identify anti-tumor compounds. Research on medicinal plants began to focus on discovery of natural products as potential leads to antitumor drugs. Medicinal plants are very interesting, have the ability to produce remarkable chemical structures with diverse biological activities. Plant-derived natural products have been used by human societies for millennia, and their biological source is most likely available and can be employed for production, have been considered as valuable sources for antitumor drugs. Many interesting natural products with biological activity are evidenced in the past few years. This review highlights the potential of natural compounds as candidates for antitumor drugs. A brief illustration of the sources and general biological effects of the main classes of plant-derived natural compounds and related molecules are also provided.

Past, present and future of rice blast management
Pooja, Kapoor

CSK HP Agricultural University, Palampur
Blast disease caused by fungal pathogen Magnaporthe oryzae is the most severe disease of rice (Oryza sativa L). On an estimate it annually destroys rice, which can feed around 60 million people. Keeping in view of the importance of the disease, various management strategies like controlled use of nitrogen fertilizers, application of silica and flooding of paddy fields are the practices in use to reduce the rice blast since long time. Improved chemical methods include utilization of copper fungicides, organomercuric and organophosphorus compounds. Some antibiotics e.g., Blasticidin S and Kasugamycin and many systemic and site specific fungicides including melanin biosynthesis inhibitors and plant activators were also utilized effectively for blast management. In the recent years leaf extracts of tulsi and bael have been found effective. Due to the highly variable nature of M. oryzae, exploitation of durable host resistance has remained a challenging job for plant pathologists and breeders. Lots of efforts have been made worldwide to study the variability in the pathogen and to find out the resistance sources. To date approximately 100 R genes for blast resistance have been mapped and 20 of these genes have been cloned in rice. Now, scientists are looking forward to develop durable resistant varieties through pyramiding of quantitative trait loci and major genes. Among the biocontrol agents, different strains of Bacillus spp. and Streptomyces sindeneusis are in use. The availability of rice and M. oryzae genome sequence data are facilitating blast resistance management program to new paradigms which includes isolation and characterization of R and Avr genes, development of noble fungicides, transformed bioagents, transgenic rice and durable resistance.

Phosphorus (P) fixation limits availability of P to plants in tropical soil, which is a major constraint for crop production. The aim of our research was to isolate, screen and characterize phosphate solubilizing bacteria (PSB) from wheat and evaluate their efficacy in P nutrition in wheat. Upon screening, 9 isolates showing varying level of phosphate solubilizing activity in both agar plate and broth assays using Pikovskaya’s medium were obtained. The pH of the culture media was decreased with increased bacterial growth suggesting that they might secrete organic acids to solubilize insoluble phosphorus. In vitro wheat seedling bioassay with two superior PSB isolates (PSB1 and PSB8) and varying sources of P revealed that both isolates significantly enhanced seedling growth (shoot and root length, shoot and root dry weight) and nutrient contents (%N, %P and %K) in plant tissue compared to control (no PSB). The performance of PSB8 was superior to PSB1 in respect of all the parameters studied. The PSB8 was tentatively identified as Pseudomonas sp. through 16S rRNA gene sequencing. Our results suggest that Pseudomonas sp. PSB8 isolated from wheat might be useful for improving P nutrition in wheat in soils with low available P.

Knowledge of the interactome improves the understanding of disease metabolism. Biological information about interactions among genes and their protein products, computationally extracted in the context of SysBiomics, can hint at molecular causes of diseases, be essential for understanding biological systems, and provide clues for new therapeutic approaches. Quick and efficient access to this data have become critical issues for biologists. We have implemented a computational platform that integrates pathway, protein–protein interaction, differentially expressed genome and literature mining data to result in comprehensive networks for insomnia and intervention effects of Jujuboside B (JuB). The interaction data were imported into Cytoscape software, a popular bioinformatics package for biological network visualization and data integration, for screening the central nodes of the network, exploiting functional study of the central node genes, exploring the mechanism of insomnia. Results showed that seven differentially expressed genes confirmed by Cytoscape as the central nodes of the network in insomnia had interactions, forming a complicated interaction network (77 nodes, 96 edges). Among gene nodes, HBA1, LEP, MAOA, PRNP, GHRL, CLOCK and SLC6A4 were verified as the genes with maximal differential expressions. Of note, we further observed that the HBA1, LEP, SLC6A4 and MAOA were JuB target genes. The interaction network of the differentially expressed genes, especially the central nodes of this network, can provide clues to the insomnia, early diagnosis and molecular targeted therapy. Our findings demonstrate that the integration of interaction network in genomic space can not only speed the genome-wide identification of drug targets but also find new applications for the existing drugs.

The objective of this study was to evaluate the selectivity/phytotoxicity of herbicides (mesotrione, nicosulfuron, and tembotrione) using the maximum quantum yield of photosystem II associated with biometric analyses. The experiment was conducted using three popcorn genotypes (BRS Angela, IAC-125 and UENF-14) and three herbicides (mesotrione, tembotrione and nicosulfuron, and a control treatment “WITH WEEDING?”. The quantum yield of photosystem II was obtained through a modulated light portable fluorometer MINI-PAM, from the chlorophyll a fluorescence. Regarding the biometric analyses, the following characteristics were evaluated: a) number medium of ears of the corn, b) grain yield in kg ha-1, c) average weight of 100 grains, and d) popping expansion. The genotypes were sensitive to tembotrione with higher intensity for the IAC - 125. The maximum quantum yield of photosystem II showed useful tool for studies of selectivity / phytotoxicity symptoms of herbicides used.

Acute effects of ferronickel slag toxicity on Chlorella vulgaris and Artemia sp. were studied. Tests were conducted on ferronickel slag to determine the concentration of heavy metals leached out to the environment. Toxicity tests were also carried out on the organisms with minimum exposure duration of 4 days or until the occurrence of a negative effect. About 400 cells mL-1 of C. vulgaris and 20 individuals of Artemia sp. were used in each of the reactors with media containing slag concentration ranged from 0 to 50%. Results showed that the IC50 (inhibition concentration) value of the percentage of slag (w/v) for C. vulgaris was 5-10%. Slag toxicity test on Artemia showed that LC50 (lethal concentration) for the percentage of slag was also between 5-10%. The study proved beyond doubt the acute effects of the slag at low concentration (10% w/v) as indicated by the inhibition of growth of 60% of the C. vulgaris population and deaths of more than 50% of the Artemia in the reactors. Hence the study suggests wise use of the slag to avoid disturbances to environment and society at large.

The emergence of citrus seedlings is influenced by several factors. One is the degree of brightness. The objective of the experiment was to evaluate the influence of four environments in the emergence of seedlings of five citrus varieties rootstocks. The work was carried out on private property located in the city of Alegre-ES, located at 20° 49’ south latitude and 41° 32’ west longitude and 322 m altitude. The experimental design was completely randomized in a split plot, with four rooms consisting of 0, 30, 50 and 80% shading in the plot and five varieties of rootstocks subplots, with four repetitions and twenty-five seeds per replicate. The rootstocks used were the Rangpur lime, lemon Volkameriano, Poncirus trifoliata, ‘Swingle’ citrumelo and Flying Dragon. After 60 days of sowing, emergence rate index, emergence percentage, leaf number and height were evaluated. At 124 days, leaf area, total chlorophyll (a + b), root dry mass and shoot were evaluated. The citric rootstocks tested responded differently when subjected to shading, and can use physiological and morphological mechanisms to maintain or even improve the emergence and seedling vigor. It was observed that the P. trifoliata rootstock obtained better performance when compared to others and that 50% shading can be adopted in this stage of citrus seedling production since it reduces seedling time in the tubes and does not affect the seedling quality.

Carboxymethyl starch as a polymeric plant based excipient in drug delivery
Anirudhan, T.S.
Department of Chemistry, University of Kerala
Parvathy, J.
Department of Chemistry, University of Kerala
Polysaccharides extracted and isolated from plant products serve as potential candidates in pharmaceutics mainly drug delivery, owing to its biodegradability, bioavailability and non-toxic character. Hydrogels, three-dimensional hydrophilic polymeric networks, exhibit dramatic changes in their swelling behaviour, network structure, and mechanical strength in response to different stimuli to the body. A wide variety of polysaccharides (chitosan, alginate, cellulose, starch, etc) and their derivatives have been used to synthesize hydrogels that tend to swell in water or biological fluids. Such systems have numerous biomedical applications including: drug delivery, wound dressing, and tissue engineering. However, single-network hydrogels have weak mechanical properties and slow response at swelling. To enhance the mechanical strength and swelling/deswelling response of hydrogels, multicomponent networks as interpenetrating polymer networks have also been reported and recently have gained much importance in research on different biomedical applications. The present review focuses on the application of carboxymethyl starch as a pharmaceutical excipient where the effect of crosslinking modification and the formation of Semi Interpenetrating Polymer Network with montmorillonite clay mineral have been investigated.

Gritsanapan, Wandee
Mahidol University
Garcinia mangostana L. or mangosteen of the Clusiaceae has traditionally been employed as medicinal drugs for decades. A plethora of compounds are responsible for a wide range of medicinal properties and biological activities. The ethanol extract of the mangosteen rind has been found to be anti-inflammatory, antioxidant and anti-acne-causing bacteria. Many research studies have confirmed its potency, with the ethanol extract of the rind being able to inhibit pro-inflammatory cytokines (TNF-?) at relatively low concentration. DPPH assay also revealed its potent radical scavenging activity. The compound responsible for the antibacterial activity, a-mangostin, was especially potent and one of the compounds responsible for the anti-bacterial activity.

Biosynthesis of the Amaryllidaceae alkaloids
Singh, Aparna
Université du Québec à Trois-Rivières
Desgagné-Penix, Isabel
Université du Québec à Trois-Rivières
Amaryllidaceae alkaloids (AAs) are a structurally diverse group of plant specialized metabolites with powerful biological activities. The medicinal properties of many AAs have been identified including the antitumor agent narciclasine and galanthamine, used for Alzheimer’s disease. Tracer studies have led to proposed pathways but AA biosynthesis remains molecularly uncharacterized. The use of systems biology-based approaches could lead to the unraveling of AA metabolic pathways. The elucidation of AA biosynthesis will provide necessary tools required to enhance AA production in plants as well as the development of microbial production platforms as an alternative to plants as a commercial source of valuable AAs.

Research Institute of Subtropical Forestry, Chinese Academy of Forestry
There are plenty of native tree species in east China, including 16 rare and endangered tree species belonging to 11 genera in 10 families. Because of narrow distribution area, weak qualitative competitiveness and reduced natural regeneration, the number of these tree species are decreasing substantially. Thus, it is necessary to protect endangered species endemic to the region. In this paper the basic data on germplasm, geographical distribution, biological characters, endangered status and current conservation strategies of rare and endangered species endemic to east China are presented. The gap areas were identified and accordingly implications were made on the future work on the native rare and endangered tree species in east China should focus on the basic research of conservation biology, establishment of the information system, solution of problems in reproductive biology and more emphasis on the key regions for protecting biodiversity.

Andargie, Mebeaselassie
Haramaya University
The present study was conducted to assess the magnitude of genetic variability, heritability in broad sense and genetic advance among thirteen mungbean accessions for some growth and grain yield characters. The study was conducted at the Haramaya University Rare research site and Hirna Research site during the 2012/2013 cropping season. Randomized Complete Block Design with three replications was used for both locations. Each genotype was planted on a 1.2 X 2m plot consisting of four rows, which accommodates ten plants per row and thus 40 plants per plot. The result showed that number of primary branches, pods per plant, seeds per plant and harvest index had high genotypic and phenotypic coefficients of variation value at both locations. For all characters, phenotypic coefficient of variation was higher than genotypic coefficient of variation indicating that there was environmental influence on these traits. The combined results for heritability showed that the high estimates of heritability and genetic advance were scored for seeds per plant and seed yield indicating that these characters were under the control of additive genetic effects. High genetic advance expected as percent of mean coupled with high heritability was observed for number of primary branches at Hirna, number of seeds per plant at Rare and number of secondary branches, pods per plant and 100seed weight for combined analysis. The present findings could be useful for establishing selection criteria for high seed yield in the mungbean breeding.

Taxonomy of the Truffles
Jamali, Samad
Razi University
Truffles are the hypogeous fruiting bodies of Ascomycete fungi that live in symbiosis with roots of trees such as oaks, hazels, poplar, etc. Due to limited morphological characters, these fungi are difficult to identify at species level. Molecular phylogenetic studies have recently demonstrated that morphological characters of hypogeous Ascomycetes can be unreliable.

Smart-use of fertilizers to manage spider mites (Acari: Tetrachynidae) and other arthropod pests
West, Katrina
The University of Western Australia
Nansen, Christian
The University of Western Australia
Fertilizers are utilized to increase productivity through improved crop growth and yield potential. However, steady declining availability of synthetic fertilizers is becoming a growing concern to the World’s food production industry. At the same time, there is increasing evidence that non-optimal (not applied at the right time and either at too high or too low dosages) applications of fertilizers may adversely affect the biochemical, physiological and morphological characteristics of crop plants, which in turn can adversely influence their resistance and/or increase their host suitability to pests. In this mini review, we discuss studies of spider mites (Acari: Tetranychidae) and their natural enemies to argue that, as part of a precision agriculture approach with temporally and spatially targeted applications, there is clear justification for more applied and basic research into smart-use of fertilizers as part of crop protection and research into “plant medicine”.

DNA polymerase ? - a novel DNA repair enzyme in higher plant genome
Roy, Sujit
Department of Chemistry, Bose Institute, 93/1 A.P.C Road, Kolkata 700009, West Bengal, India
DNA polymerase lambda (Pol ?) is a novel family X DNA polymerase which has been shown to play key role in nuclear DNA repair and meiotic recombination. Recent studies in mammals support function of this enzyme in base excision repair in response to oxidative DNA damage. However, in plants the biological function of Pol ? in oxidative stress response is still largely unknown. This review will survey recent advances in our understanding of role of Pol ? in repair of oxidative DNA damages and its possible potential involvement in plant’s base excision repair (BER) pathway in response to oxidative stress.

Impact of Pyraclostrobin (F-500) on Crop Plants
Kanungo, Mansi
Joshi, Juhie
Strobilurins, such as pyraclostrobin, belong to a fungicide group with preventative mode of action and are used around the world. Strobilurins inhibit mitochondrial respiration by stopping electron transfer at the quinol oxidation site in the cytochrome-bc1 complex which disrupts energy cycle of the fungus. F-500 (pyraclostrobin) strobilurin, a new generation broad spectrum fungicide has been shown to cause changes in the metabolism of plants resulting in higher biomass and yield. Considering the ever increasing demand for food production with shrinking cultivable area day by day, it is necessary to go for agrochemicals which enhance the growth and development vis-à-vis productivity.

UV exclusion studies can provide the realistic assessments of sensitivity of plant to current level of UV radiation. Perusal of relevant literature reveals that UV exclusion causes enormous increase in the growth of aerial parts along with below ground parts of the plants. Exclusion of UV-B (280-315 nm) and UV-A+B (280-400 nm) enhanced the photosynthetic pigments, net photosynthetic rate and stomatal conductance along with remarkable increase in the activity of Carbonic anhydrase, Rubisco and PEPCase. UV excluded plants have higher PS II efficiency, reducing power, CO2 fixation and decreased UV-B absorbing compounds, channeling the additional fixation of carbon to improvement of yield. UV exclusion studies indicate that dicot plants are more sensitive than the monocot plants to current level of UV-B.

Grapevine rootstock effects on abiotic stress tolerance
Corso, Massimiliano
University of Padova
Bonghi, Claudio
University of Padova
Amongst 60 species within the Vitis genus, Vitis vinifera L. is the mostly used species for the production of wine and distilled liquors. Before the devastation of European viticulture caused by the introduction of phylloxera from North America, varieties of V. vinifera used commercially for wine production in Europe were traditionally grown on their own roots. Subsequently, the use of rootstocks from the pest’s origin was introduced to provide resistance to this and other deleterious diseases and to save the fate of European viticulture. Rootstocks have been bred from a number of Vitis species and are known, in addition to the enhanced resistance to phylloxera and other pathogens, confer tolerance to abiotic stresses (e.g. drought, high salinity and Fe-deficiency) and to alter specific aspects of harvest/postharvest fruit quality of a scion. This review summarizes recent data related to the responses of grapevine rootstocks to abiotic stresses, with particular attention to drought, salinity and iron chlorosis.

Electrospun plant-derived natural biomaterials for Tissue engineering
Venugopal, Jayarama Reddy
National University of Singapore
Sridhar, Sreepathy
National University of Singapore
Ramakrishna, Seeram
National University of Singapore
Plant-derived natural products are being used in medicine, and they are easily available for the production and use in tissue engineering based biological applications. Utilization of plant materials to treat human diseases is a common practice followed over many decades. In fact plant and its derivatives have been actively included in health management over thousands of years. The advent of phytochemical and phytopharmacological sciences has opened an arena to elucidate the structural and biological composition of several medicinal plant products. Their pharmacological effects depend on the supply of highly active water soluble compounds; however, due to their large molecular size most compounds are unable to cross the lipid membranes of the cells and therefore result in poor absorption resulting in loss of bioavailability and efficacy. Electrospinning makes it possible to combine the advantages of utilizing these plant materials in the form of nanofibrous scaffolds for delivering the active constituent at a sufficient concentration during the entire treatment period to the host site. The aim of this review is to highlight the potential applications of electrospun nanofibrous scaffolds based systems and herbal medicines in tissue engineering.

Conservation relevance of terrestrial herbaceous vegetation studies
Willie, Jacob
(i) Terrestrial Ecology Unit, Ghent University and (ii) Project Grands Singes, Center for Research and Conservation, Royal Zoological Society of Antwerp
Herbaceous vegetation studies are pivotal for a better understanding of the ecology of several animal species that use these plants as food items, nest-building materials, and tools. This article illustrates how such investigations can build on the knowledge base required for conservation planning and help to assess habitat quality. Although many descriptive studies on herbaceous plants used by animals have been carried out, more research effort is needed to address questions such as diversity, community composition, population dynamics, and the influence of abiotic factors. This investment would result in more accurate estimations of resource availability and a better understanding of the effects of abiotic factors on herbaceous plants and dependent animal species.

Glycosylation is the most common posttranslational modification of proteins and consists of the addition of sugar moiety to proteins. The resulting glycosylated proteins are often secreted to the extracellular compartment or integrated into different cell organelles. This modification was identified in plant as well as in mammalian cells. A number of plant and mammal proteins are either N- or O-glycosylated. This review focuses on O-glycosylation which refers to linkage of a glycan to hydroxyl group of serine, threonine or proline residues. O-glycosylation can be altered by the action of chemical inhibitors. For instance, 3,4-dehydro-L-proline, ethyl 3,4-dehydroxy benzoate and a,a-dipyridyl inhibit the activity of prolyl4-hydroxylase, a key enzyme for plant O-glycosylation. In addition, a small molecule inhibitor designated 1-68A inhibits the polypeptide N-acetylgalactosaminyltransferases of mammalian cells. The aim of this review is to summarize the role and mechanism of action of these inhibitors of O-glycosylation and their impact on cell development in plants and mammals.

Plant molecular pharming is a promising concept based on the large-scale production of recombinant proteins encompassing antibodies, vaccines and enzymes for human or veterinary uses and treatments. This new branch of biopharmaceutical industry offers pratcical and safety advantages over other traditional production systems. In higher plants, the complex cellular machinery makes possible synthesis and posttranslational modifications of heterologous protein macromolecules. The limiting obstacle to using this plant system at industrial scale is most often the low yield of the recombinant proteins. To improve this production level, many studies have been focusing on the choice of plant species, tissues, organs and cell suspension cultures or various upstream and downstream constituents in the expression cassettes. Likewise, new engineering technologies in plant molecular pharming have emerged relying on the usefulness of using soybean agglutinin (SBA), hydrophobin, zein and elastin-like peptide tags which are employed to extract and purify recombinant proteins in some host systems and under the control, and as a part, of different expression cassettes. Known to be very useful tools in recombinant proteins linkers separate different domains or units of the heterologous gene and thereby keep the functionality of the protein of interest. Here, we compare computationally one tag SBA as a part of fusion with a pharmaceutical human protein ADA joint directly or by the specific flexible (GGGGS)3 liker. The in silico analysis focuses on the mRNAs stability and fusions of tagged and tagged-linked ADA recombinant proteins.

The associations of yield and its components offer important information in breeding plants. A study was conducted at the Araka Agricultural Research Center, Hossana, Ethiopia during 2012 growing season under rain fed condition on 18 potato genotypes/varieties to determine the association of yield and its components. The association was analyzed by correlation coefficient, and further subjected by path coefficient analysis to estimate direct and indirect effects of each character on tuber yield. Positive and significant correlation were found between tuber yield and biological yield, plant height and tuber yield, stems per plant and tuber per plant. The genotypic correlation coefficients were higher than the corresponding phenotypic correlation coefficients for most of the characters indicating the inherent association among the characters. Path analysis of tuber yield and its components shows that stems per plant, biological yield and harvest index exerted positive highest direct influence on tuber yield indicating their importance as selection index for yield improvement.

First report of Septoria silybi associated with leaf blotch of Silybum marianum from Iran
Jamali, Samad
Department of Plant Protection, College of Agriculture, Razi University, Kermanshah, Iran
During March to April 2013, in the course of routine sample collection, a leaf spot disease was observed on Silybum marianum in different areas of Kermanshah province, Iran. Initial symptoms of the disease were pale brown, necrotic lesions, mostly 8-10 mm long on leaves. On the surface of the infected leaves conidiomata were observed, which were pycnidial, amphigenous, scattered, dark brown to blackish, globose, immersed in host tissue, becoming partly erumpent, unilocular, 90-150 µm in diameter, with an ostiole of 18-24 µm in diameter. Conidiogenesis was enteroblastic. Conidia were hyaline, filiform, sub-straight to mildly flexuous, truncate at the base, 20-48 × 1.2-2.8 µm, 2-5-septate, with indistinct septa. On the basis of symptoms, fungal morphology and completion of Koch’s postulate, the fungal isolates from the leaf spots were identified as Septoria silybi. This is the first report of S. silybi on leaves of S. marianum in Iran.

A pilot reed bed study was conducted with the aid of aeration to remove lead (Pb) contaminated water using Scirpus grossus L. f. The plants were grown in sand medium in pilot-scale reed beds, and exposed to water containing Pb in a various concentration (10, 30 and 50 mg/L) with aeration rate of 2 L/min. The samples were taken on day-1, day-14, day-28, day-42, day-70 and day-98. The results showed that Pb concentration in water decreased 74% on day-7, 80% on day-14, 99% on day-28 and reach 100% on day-48 for treatment 10 mg/L. Pb concentration decreased 91% on day-7, 93% on day-14 and then on the day-28 the reduction reached 99% for treatment of 30 mg/L. For Pb treatment of 50 mg/L, the reduction reached 92% on day-7, 96% on day-14, and 99% on day-28. The sand adsorbed Pb up to 7.91×10-4 mg/kg for 10 mg/L, 1.07×10-3 mg/kg for 30 mg/L and 2.41×10-3 mg/kg for 50 mg/L. Pb uptake by plant was 2286 mg/kg on day-98, 4174 mg/L on day-28 and 8297 mg/kg on day-14 for 10, 30 and 50 mg/L, respectively. The highest Bioaccumulation Concentration (BC) was 10618 for 10 mg/L on day-28, 81311 for 30 mg/L and 81467 for 50 mg/L both on day-42, with the Translocation Factor (TF) related to the same day of these BC were 0.13, 0.24, and 0.35 respectively. The highest TF value for 10 mg/L were 0.7 on day-98, 0.38 for 30 mg/L on day-70 and 0.59 for 50 mg/L on day-14.

Albinism is a common problem encountering breeding and interspecific crosses. Arabidopsis thaliana chyB (AtchyB) gene encodes for ß-carotene hydroxylase. We generated transgenic plant over-expressing AtchyB in A. thaliana and compared to wild-type (WT) plants in response to light stress. We tested whether the over-expression of AtchyB gene can affect the green and albino leaf ultrastructure in A. thaliana transgenic lines. In this study, over-expression of AtchyB cDNA governed by Cauliflower Mosaic_Virus_35S (CaMV 35S) promoter showed a progressive yellow coloration in primary leaves and ultrastructural changes to albino and green leaves of transgenic A. thaliana plant in comparison to wild type (WT). Leaf albinism causes dilatation of both the palisade parenchyma and the secretory cells, enlargement of plastoglobules and increased cuticle thickness. In addition, the presence of low number of chloroplasts and/or starch grains is associated with leaf albinism phenomenon. Altogether, this suggests that A. thaliana 35S:AtchyB transgenic lines induce leaf albinism which affects the leaves ultrastructure with retrograde signaling, defects in chlorophyll biosynthesis and chloroplast dysfunction.

Leaf and stem materials of Achyranthes coynei and Achyranthes aspera were used for HPTLC analysis. HPTLC plates were developed on n-hexane: ethyl acetate (5:1 v/v) solvent system. The densitometric profiles were evaluated to elucidate differences within and among the species. The Rf values and number of peaks obtained in densitrogram indicated chemical variation in the species. Although, both species had more or less equal number of peaks, their Rf values, %height and %area varied. Thus HPTLC analysis in absence of external standards, proved to be an informative tool for evaluating differences between these species and their parts.

Post-traumatic stress disorder (PTSD) is a devastating neuropsychological disorder that may develop in response to traumatic experiences. Symptoms include anxiety, hypervigilance, memory deficits, and depression. We investigated L-Theanine on neurobehavioral effects in a PTSD rodent model. Evaluation of the effects of L-Theanine as a sole agent and in combination with midazolam on neurobehavior was analyzed using the Elevated Plus-Maze, Morris Water Maze, and Forced Swim Test. Statistical analysis consisted of comparison of PTSD symptoms in PTSD vs. non-stressed groups. Data regarding weight gain between the 40 control (non-stressed) and 40 PTSD (stressed) rats were significantly different (p < 0.001), where the control rats gained an average of 55.4 grams compared to 37.4 grams for the PTSD rats over the 10 post stress days. This research did not show statistical significance with single dose administration of L-Theanine or in combination with midazolam. However, the theoretic framework and Post-Traumatic Stress Disease Induction Model were validated based on this research. This study establishes a solid framework for future investigation of PTSD treatments. Future studies of L-Theanine and other herbal therapies may use an extended dosing period to obtain a steady state for the period of time needed to alter neurobiology.

Henna plant belongs to continental oases where water shortage constitutes the essential limiting factors of its agricultural production. Lawsonia inermis L. (Lytraceae) is often exposed to severe drought stress in Gabes; a Tunisian arid region. The present study was carried out to evaluate the impact of water stress on the morphology of Tunisian henna plants. Thus, an experiment of four months was carried out under greenhouse at the Institute of Arid Region in Medenine, Tunisia. Henna was exposed to three different irrigation regimes, whereby the plants where irrigated to field capacity (control, T0), 50% of the control (moderate stress, T1) and 25% of the control (severe deficit irrigation, T2). Results showed that, leaf area (LA), leaf number and stem length of henna, decreased in response to the studied stress. The effect of water stress was clearly observed on those parameters. Moderate drought (T1) did not damage henna morphology, and the plants grew better than without water limitation (T0). Furthermore, the water stress-typical responses were shown as time and severity dependent in all the measured parameters. Indeed, lowest water availability treatment (T2) induced significant decrease in total number of leaves, as well as reductions in LA. Under this severe water stress (T2); LA was reduced by 65.79%, compared to control, at 60 days after the initiation of the bioassay. Stem length decreased significantly in the most severe water stress, this reduction was about 44%. Globally, we conclude that henna plant growth decreased progressively to long-term water limitation.

This study aimed to evaluate the initial development of the nodulating legumes jurema-rosa (Mimosa verrucosa Benth.) and angico [Anadenanthera colubrina (Vell.) Brenan] and the non-nodulating legumes umburana-de-cheiro [Amburana cearensis (Allemao) A.C. Smith] and caatingueira-verdadeira [Poincianella pyramidalis (Tul.) L.P. Queiroz]. Plants were grown in pots containing soil samples from six areas in Brazilian Caatinga biome region. Differences at the nodulation in plant roots were observed among the soils studied, pointing out a Vertisol covered by an introduced legume. The leaf gas exchange evaluations also showed differences among the plants grown in the different soils used as substrate mainly to angico and caatingueira-verdadeira.

Plants apply several strategies that are developed during their evolution and artificial domestication to overcome biotic and abiotic stresses. Among eminent environmental threats drought stress is a major factor that affects plants at physiological, biochemical and molecular level. Blackgram (Vigna mungo) is an important pulse crop but its productivity is adversely affected by drought. In the present work, different cultivars of blackgram i.e. T9, RBU38 and VM4 are taken to find out the effects of drought stress by the estimation of different biochemical parameters to better understand biochemical pathway modulations under stress and its possible mitigation. Damage to photosynthetic machinery as evident by decrease in chlorophyll content and loss of membrane integrity in the plants under drought stress. The adverse effects of drought on the plants were averted to a certain extent in RBU38 by activation of defence signalling through H2O2 at lower concentration, which proved damaging at high concentration for T9 and VM4 and a concurrent increase in proline content which may provide protection against oxidative stress. This study suggests that drought modulated biochemical parameters can be used as reliable indices for selection of genotypes with a better stress tolerance.

Population Graphs includes network theory to infer the relationship among individuals or populations and their respective roles. The hypothesis for this work establishes that Argentinean natural populations of Anadenanthera colubrina var. cebil keep ancestral polymorphism as a consequence of continuous historical distribution of this species in South America. Network analyses were performed centered on individuals and populations using two different measures which integrate genetic information in terms of time and divergence history. These analyses allow us to conclude that the populations of A. colubrina var. cebil display geographical isolation even though they are historically related.

Relation between 6-gingerol content and antioxidant activity in in vitro grown cultures of ginger was studied. Reverse phase HPLC analysis revealed that rhizome derived callus culture and micropropagated plants produced lowest amount of 6-gingerol compare to conventionally grown plants. The antioxidant activity of extracts was determined using 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging assay and Ferric Reducing power assay (FRAP) and correlated with the content of total phenolics and total flavonoids in the extracts. Strong correlation was found between antioxidant activity, total phenolics and 6- gingerol content.

We present here an efficient micropropagation protocol through direct regeneration of plants from meristemoids in Anthurium andraeanum Linden cv. Tinora. About 96.6±0.33 of in vitro grown nodal segments having axillary buds were induced to form meristemoids on modified MS basal medium supplemented with 0.92 µM Thidiazuron (TDZ). The significantly highest numbers of shoots (25.6±0.23) were regenerated from 93.3±0.33% of meristemoids in the same culture medium. The histological and scanning electron microscopic (SEM) study confirmed direct organogenesis from the meristemoid.

With the aim of studying the effect of the irrigation rate on the yield and fruit quality of sweet orange (Citrus sinensis (L.) Osbeck) cv. Folha Murcha, an experiment was conducted in Sítio Jacutinga located in the county of Jeronimo Monteiro, Espirito Santo, Brazil, using orange of the variety Folha Murcha grafted on mandarim Cleópatra, with five years of age, spaced 5 m between rows and 4 m between plants within the line. Five treatments were implemented each with a different irrigation regime (L0 = without irrigation; L1 = 50% of PET; L2 = 75% of PET; L3 = 100% of PET and L4 = 125% of PET), defined based on potential evapotranspiration estimated by the method of Tank Class A. the experimental design was a randomized block with three replications consisting of nine plants in each repetition. In this study, yield per plant (kg), diameter and height of the fruit were evaluated. The irrigation regime 125% of the PET promoted the highest yield of orange Folha Murcha, under the conditions of this study.

Parthenium hysterophorus L. is a harmful weed of family Asteraceae (Compositae). Its chemical constituents and ethnobotanical uses have been reviewed in this paper. The reported phytochemical studies revealed the presence of flavonoids, oils, phenolics, terpenoids, amino acids, alkaloids and others. Different parts of the plant have been reported to be used in traditional medicine against fever, diarrhoea, neurologic disorders, urinary tract infections, dysentery, malaria and as emmenagogue. It is also used as remedy for inflammation, eczema, skin rashes, herpes, rheumatic pain, cold, heart trouble and gynaecological ailments. Although plenty of compounds were isolated from this plant, further work needs to be carried out and explore folk recipes for the benefit of improving human health.

Two Italian isolates of Malva vein clearing virus (MVCV), naturally infecting Malva sylvestris (common mallow) plants, were characterized at biological, serological and molecular level. Experimental host range was comparable for both isolates and in agreement with those reported for other MVCV isolates. Cytopathology observed indicated type I of cylindrical inclusions caused by both isolates in common mallow. The 3’ genome extremity of about 1800 nucleotides was sequenced for both isolates. It comprised of the 3’ end of the NIb gene, the entire putative ORF of the coat protein (CP) and the 3’ non-translated region of genome. Phylogenetic analysis based on CP gene did not shown any statistically significant grouping among ten different MVCV isolates, suggesting low level of variability among the MVCV isolates genetically characterized until now.

In present investigation, an efficient Agrobacterium- mediated genetic transformation was successfully carried out for a well known date palm (Phoenix dactylifera L.) cultivar “Khalasah” using matured somatic embryos. Somatic embryogenesis was initiated from offshoot’s shoot tips of date palm cultivar. For genetic transformation, morphologically advanced matured somatic embryos developed on MS medium fortified with TDZ (1.0 mg/l) were co-cultured with A. tumefaciens strain LBA 4404 harboring binary vector pBI 121, containing uidA (GUS) and npt II genes and incubated for 4 days and later it was (somatic embryos) inoculated on germinating and plantlet conversion MS medium supplemented with BAP (0.75 mg/l) + kanamycin (100 mg/l). Prolific shoots developed from putatively transformed matured embryos showed 47.5 % transformation efficiency. A large number of transgenic plants were obtained and later established in black hard plastic bags. A strong GUS activity was detected in the putatively transformed plant leaves by histochemical assay and, the integration of uidA (GUS) and npt II genes into transgenic plants was confirmed by polymerase chain reaction (PCR) and Southern hybridization analysis. The established transformation protocol allows effective and quick regeneration via somatic embryogenesis, and it would be highly valuable for existing date palm orchards and improving their productivity.

This study aimed to evaluate the effects of seasonality on mycorrhizal colonization characteristics as hyphal, vesicular and arbuscular colonization with some medicinal plants species of Chittagong BCSIR forest of Bangladesh. Ten highly valued medicinal plants were selected randomly from Chittagong BCSIR forest to conduct the research. Root samples were collected and examined to determine fungal colonization in three times (Dry, Rainy and Winter) during the year in 2014. The result revealed that the medicinal plants of BCSIR forest were mycorrhizal. The highest hyphal colonization was obtained during rainy season of the corresponding year but decreased during dry and winter season. Vesicular colonization was attenuated during rainy season but increased in dry and winter season but arbuscular colonization was higher proportion in rainy and winter season whereas arbuscular colonization reduced in dry season. This result indicates that AMF colonization varies seasonally as well as depending on some factors like as climate, edaphic, plant host relationship and species diversity.

This paper proposes that exposure to radiation could generate free radicals, which could lead to disorders such as heamolysis-induced anaemia. We evaluated the radioprotective potentials of Cochorous olitorious and Adasonia digitata methanol leaves extract in gamma radiation induced anaemia. Fifty four adult male Wistar rats were divided into nine groups of 6 animals. Except for the control group, the other the animals were treated with a single dose of whole body gamma radiation of 6Gy and received either 500 or 1000 mg/kg body weight (bwt) of A. digitata and C. olitorious either singly or combination and vitamin C was used as reference. A. digitata and C. olitorious were screened for phytochemical content and had saponin (16.59±1.85 and 22.12±0.24), tannins (311.98±0.01 and 287.07±0.16), polyphenols (170.90±0.68 and 330.07±0.32), alkaloids (81.56±0.56 and 68.65±2.05) and flavonoids (25.38±2.88 and 157.38±0.38) respectively. There was significant loss in body weight, depletion in red blood cells (RBC), packed cell volume (PCV), heamoglobin concentration (HBC) in untreated rats exposed to gamma radiation. Administration of the plant extract to rats exposed to radiation was able to attenuate and ameliorate loss in body weight and changes in blood cells (HBC, PCV, PLT and RBC) especially in radiated rats on combination therapy of both extracts at 1000 mg/kg bwt group. Hepatoprotective and safety evaluation was done by measuring the serum ALT, AST and ALP, these parameters were significantly (p<0.05) increased in untreated rats exposed to gamma radiation compared to normal control rats and these decreased in rats on plant extract.

Taxonomic significance of Cyspsela in Vernonia anthelmintica Willd. and V. cinerea Less. (Asteraceae; tribe – Vernonieae): Structural manifestations
Talukdar, Tulika
Deptt. of Botany, APC. ROY Govt. College, Siliguri, West Bengal
An investigation was carried out to reveal the taxonomic importance of cypselar features of Vernonia anthelmintica Willd. and Vernonia cinerea Less. through morpho-anatomical manifestations in the plesiomorphic tribe Vernonieae of the dicot family Asteraceae. A light microscopic (LM) and Scanning Electron Microscopic (SEM) study unraveled various morphological features of the cypsela. Among them, apical part, wall surface, surface hairs, nature, structure and arrangement of carpopodium, and stylopodium are taxonomically important traits. Furthermore, presence or absence of glands in wall surface, pappus bristles, testal nature, distribution of crystal and in pericarp and/or testa and endosperms of cypselas can also be considered as taxonomically significant. Distinct differences were observed between two taxa for many characteristics. Notable among these were occurrence of stylopodium, size of cypsela (without pappus), nature of pappus, thickness of pericarp, presence or absence of ribs, layer of radially elongated cells in mesocarpic sclerenchyma ans parenchyma, presence of additional uniseriate palisade like sclerenchymatous layer in V. anthelmintica, but not in V. cinerea, testal epidermal layer, nature of endosperm layer, and crystal formation. Similarities between two taxa were also noted. Based on structural manifestations of cypsela at morpho-anatomical levels, an indented dichotomous key is provided for identification of studied taxa.

The present study undertakes an enumeration of the existing flora species around Awba dam, located within the University of Ibadan, Ibadan, Nigeria. Methods followed conventional practice as reported by previous authors of related studies. Findings showed that the study area is very rich in biodiversity. A total of 119 species in 47 families were recorded. The large number of species recorded, especially herbs which contribute 37% of the total enumeration suggest that the site may be further accessed for medicinal plant species which could possess beneficial health properties. Nonetheless, the presence of fauna and phytoplankton species also indicates their role in ecosystem balancing and thus sustaining human livelihood. With the continuous developmental activities, practical conservation approaches is ideal if the study area is to be saved from total loss of species.

Sodium fluoride (NaF) induced changes in growth and DNA profile of Vigna radiata
Agarwal, Swati

Khan, Suphiya
Department of Bios Science and Biotechnology, Banasthali Vidyapith (Raj)
Fluoride (F) is a natural, ubiquitous, non-biodegradable and hazardous pollutant. To investigate its effect, Vigna radiata seeds were treated with NaF (0, 25, 50, 75, 100 mg NaF kg-1) and its effect was studied on germination, growth and RAPD profile. The variation in DNA profile in response to NaF treatment was detected by RAPD-PCR technique. The result of RAPD was observed in terms of GTS% (Genomic Template Stability). Results showed that there was gradual decrease in GTS% i.e. increase in DNA damage from 25 to 75 mg NaF kg-1 concentration. These data demonstrate that RAPD is a reliable tool and permits greater insights into the genetic alteration of V. radiata.

Bryophytes from the Fiji Islands, VII. Cololejeunea renneri sp. nov. (Lejeuneaceae, Marchantiophyta)
Pócs, Tamás
Eszterházy Károly College
During the biodiversity research of Fiji Islands Matt A.M Renner has collected a Cololejeunea species related to Cololejeunea filidens Benedix, widespread in the Indomalesian region, but well differs by its short, unicellular second lobular tooth and by its thin cell walls without trigones and intermediate thickenings. It is described as Cololejeunea renneri Pócs. With this the number of Cololejeunea species known from Fiji Islands raised to 43. The new species might be more widespread in the Indomalesian-Pacific region, just confused before with Cololejeunea filidens.

An update on sequenced chloroplast genomes of Bryophytes
Shanker, Asheesh
Banasthali University
The sequencing of complete chloroplast genome of Marchantia polymorpha paved the way to know the structure and organization of chloroplast genomes of other plants. Since then ~747 chloroplast genomes have been sequenced. However, in comparison to the tracheophytes, a small number of complete chloroplast genome sequences of bryophytes are available (only 4 liverworts, 6 mosses and 2 hornwort). This review represents an update on sequenced chloroplast genomes of bryophytes.

Hornwort diversity at Pachmarhi Biosphere Reserve (Madhya Pradesh), India
Asthana, Ashish Kumar
National Botanical Research Institute
Gupta, Reesa
National Botanical Research Institute
Pachmarhi Biosphere Reserve (PBR) has been a major spot of biodiversity in central India, particularly in terms of cryptogamic flora. Hornworts are the group of bryophytes placed under Division Anthocerotophtya which form a significant assemblage with phylogenetic and evolutionary importance as these plants possess characteristics that relate to the vascular plants. As a result their taxonomic studies, diversity assessment and understanding of their affinities hold much importance. India harbours 39 hornwort taxa, out of which nine have been listed from PBR. Among these five taxa viz. Anthoceros bharadwajii Udar et Asthana, Phaeoceros carolinianus (Michx.) Prosk., P. kashyapii Asthana et Sriv., P. laevis (L.) Prosk.and P. udarii Asthana et Nathhave been encountered from the study area. The total diversity of hornworts at PBR, including the previously listed taxa and those elucidated in the present study suggests that these plants contribute substantially towards the bryophyte diversity of the Biosphere Reserve.

Vinca pusilla Murr. is a traditional medicinal plant used to treat several diseases. To substantiate the traditional medicinal utility of the plant, the present study aims at screening the antimicrobial activity of methanolic extracts of leaves and roots against five Gram positive, five Gram negative bacterial and four fungal strains. The minimum inhibitory concentration (MIC) were determined by two fold dilution assay. The results indicated that, leaf and root extracts were more effective on Bacillus subtilis and Staphylococcus aureus strains (MIC < 1 mg/mL). The tested organisms were sensitive to root extract compared to leaf extract. Fungal strains were resistant than the bacterial strains to both the extracts. Thus the present study illustrates the antimicrobial potential of the plant.

Taxonomic studies of the genus Tephrosia Pers. (Papilionaceae) in Nigeria
Chukwuma, Deborah M
Department of Plant Science and Biotechnology, Federal University, Oye-Ekiti
Ayodele, Emmanuel A
Department of Botany, University of Ibadan, Ibadan
The relationship between eleven Tephrosia species occurring in Nigeria was examined using a number of taxonomic tools. Fresh and herbarium specimens were used for this purpose and methods followed conventional taxonomic practice. Although the species occur in savanna ecosystems, herbarium collections revealed an abundant distribution in the southern part of Nigeria. Morphometric studies revealed that four quantitative characters viz: leaflet length, lamina length, fruit length and pedicel length can be used to delimit members of this genus. Based on the cluster analysis using average linkage within group, the closest species are T. leptostachya and T. purpurea with the shortest distance measure (0.713). T. linearis has the smallest leaflet, in length and width. Further morphological studies also showed that T. vogelii has the largest pod while T. barbigera has the highest number of seeds per pod. Generally, the species have very short petiolule ranging between 0.2cm and 0.3cm in length, on the average. Foliar micro-morphological studies also showed that the species generally possess polygonal cells with straight to curved anticlinal walls and anisocytic stomata types while pollen studies revealed tricolporate pollen grains to be predominant within the taxa. Although, the present study has added to the existing information regarding Tephrosia species, it also suggests further research to ascertain its taxonomic position within the Papilionaceae.

This paper deals with the details variation of petal venation in Kallstroemia pubescens of the family Zygophyllaceae. In the present study, from a pool of 100 petals, 40 petals were selected randomly to observe the variation of venation patterns of petals in different flowers of same species collected from different population of the same ecological area. All the 40 petals examined, as per Foster’s classification, shows various type of anastomoses. Detailed study reveals that after the entry of a single vain in a petal, it divided into two costals and one median. Actually anastomosis takes place between the sister’s branches of the costal or between a branch of the costal and a branch of the medion. Present observation on the anastomosis of the petal venation of the K. pubescens is clearly fits with the study of Foster (1968). At the basal region of petal, Type-I(35.2%) and Type-II(35.2%) are more prevalent, than Type-III (5.8%), Type-VI (5.8%) and Type-V (17.5%).At the middle region of petal, Type-II (47.56%) is more prevalent than Type-I (17.07%), Type-V (13.41%), Type-III (13.41%), Type-IV (4.8%) and Type-VI (3.65%). At the distal region, Type-II (44.7%) is more prevalent than Type-III (33.33%), Type-I (10.41%), Type-V (8.33 %), Type-VI (2.08 %) and Type-IV (1.04 %).

RETRACTION - 24 June 2016
With objectives to assess molecular diversity and digitization of molecular data in relation to invasive potential of Lantana camara L., leaves of 12 ecotypes collected from five different eco-climatic zones of Eastern Indian state of West Bengal, were subjected to RAPD fingerprinting. Invasive potential (IP) was assessed by allelopathic effects of Lantana leaf extracts on seed germination of target crop (lentil), relative competition intensity (RCI) between weed and target crop and abundance (AB) of Lantana in quadrats. Genetic diversity was found between zones and between ecotypes within a zone. Polymorphism varied 25-70 % with highest magnitude was found in Indo-Gangetic Basin, followed by Western dry land, and parts of temperate and sub-Himalayan zones of Indian Himalayas. Moderate polymorphism with 50 % polymorphic markers was observed in coastal ecotypes. Strong positive correlation existed between polymorphism %, IP, RCI and AB, and 12 ecotypes were clearly distinguished in four categories of invasiveness. IP1 represented worst invasiveness in Gangetic basin and Western dry land while the lowest (IP4) was observed in parts of temperate and sub-Himalayan region. The ‘Darjeeling’ ecotype in temperate Himalayas (2000 m, msl) was identified as moderately-high invasive (IP2 category), possessing two unique RAPD markers. Phylogenetic tree revealed nine groups of 12 ecotypes exhibiting close similarity within coastal zones and within Western dry land ecotypes. The data are now being digitized using bio computation tools/software in a bio-digital platform ‘LANRAD’ (Lantana Random Amplified DNA), as the first eco-genomic on-line platform of an alien invasive plant in India.

Solid residues produced by processing food waste via Microaerobic Fermentation (MF) and by Black Soldier Fly larvae (BSFL) have been proposed as soil fertilizers. Yet, little is known about their effects on plant growth. This study compares the growth of corn plants (Zea mays) in soil amended with MF or BSFL residue, with effects of aerated compost on corn growth over ten weeks. Corn plants grown in soil amended with MF residues were 109% taller and had 14% more leaves than those grown in traditional aerated compost (Cedar Grove). But plants grown in BSFL residues were stunted, growing 39% shorter and having 19% fewer leaves on average. Only height data was statistically significant. Results indicate that MF produced from food scraps is a suitable soil amendment product, but BSFL solid residue from a similar source is phytotoxic when amended, untreated, into soil in a ratio of one part residue to two parts soil. More research on additional post-processing methods for BSFL solid residue is needed.

This review spotlights on recent indications that recognizes potential cellular mechanisms that may be involved in the tolerance of salicylic acid (SA)-treated seedlings to the presence of cadmium (Cd) in their environment. It appears probable that SA stimulates signaling systems implicated in plant defense-related actions against Cd-induced oxidative stress. These include mechanisms that reduce uptake of metals into the cytosol by extracellular chelation through extruded ligands and binding onto cell-wall constituents. Cellular chelation of metals in the cytosol by a range of ligands (peptides, phytochelatins (PCs)), or increased efflux from the cytosol out of the cell or into sequestering compartments are also key mechanisms improving tolerance. Free-radical scavenging capacities through the activity of antioxidant enzymes or production of peptides and PCs add another line of defense against the toxic effect of Cd. The SA signaling events can be attributed to the extracellular SA perception model in which reactions between SA and apoplastic proteins result in acute oxidative burst under Cd stress.

Cadmium (Cd) has become one of the major metal stresses which pose a serious threat to plants and animals. In this context, endogenous and exogenous salicylic acid (SA) could play an important role in mitigating the uptake of the Cd ions and providing immunity to plants against the heavy metal stress. SA enhances the resistance capacity of contaminated plants, which, however, depends on the metal concentration and the duration of the treatment. Moreover, SA is considered as a promising signal molecule for improving the efficiency of phytoremediation, and, consequently, growing of safe crops in metal polluted areas. The recent developments in the probable mechanisms by which SA could enhance the tolerance of plants to heavy metals and how it could have an effect on phytoremediation of Cd from contaminated soils are discussed.

Mukherjee, Sobhan Kumar
University of Kalyani
Mangroves are extremely important bio-resources that are crucial to coastal environment. Indian mangrove vegetation covers about 6,756 sq. km. Along the 7516.6 km long coast line, including island territories. Estimates of the number of species considered, mangroves in the world ranges from 50-90, and in India from 50-60. Mangroves are declining rapidly as they are getting degraded for agriculture, aquaculture, tourism, urban development and over exploitation. India lost 40% of its mangrove area during the last century. The present work is focused on assessing the status of mangrove area in India with special reference to the Lothian Island Wildlife Sanctuary in Sundarbans. Total 30 species were collected during the field visits. Among them 16 species are major mangroves and 14 are mangrove associates. Effective governance structures, better planning for rehabilitation of degraded mangroves, education and awareness building in local communities are needed to conserve, protect and restore the valuable mangrove wetland ecosystems.

An in vitro experiment was carried out to evaluate the effectiveness of antibiotics at different concentrations on growth and development of Trichoderma harzianum, Phytophthora infestans, Colletotrichum gloeosporioides, Corticium theae and Fusarium oxysporum found in tea plantation. Three samples viz. sample-1 (Validamycin 60% w/w) @ 45, 60 and 75 ppm, sample-2 (Hexaconazole 2.5% w/w+Validamycin 8.5% w/w) @ 55, 82.5 and 110 ppm and sample-3 (Streptomycin 9% w/w+Tetracyclin hydrochloride 1% w/w) @ 50, 75 and 100 ppm were tested. The result showed that Antibiotics have inhibitory effects on T. harzianum. Unsatisfactory performances in terms of per cent growth inhibition (<80) were recorded on crop infecting fungi. C. theae treated with sample-1 @ 75 ppm and C. gloeosporioides with sample-2 @ 110 ppm had shown maximum 25.50 and 54.19 per cent growth inhibition, respectively. The highest 70.53 per cent growth inhibition of C. theae was observed in sample-3 treated @ 100 ppm. Considering the findings it can be recommended not to use above antibiotics with their respective concentrations in plant agriculture for controlling diseases caused by the said fungi.

In the present Investigation Salvinia natans L exposed to increasing concentration of Al stress and its interaction with polyamine was discussed. Among the physiological attributes Glutathione-S-transferase, glutathione peroxidase activities were up regulated against control. At transcript level glutathione peroxidase was also shown by over-expressed manner to support the lyses of peroxide. However, the application of Put had minimized these activities with same way to establish the role of polyamine under metal stress. In secondary metabolites synthetic pathway phenyl alanine ammonia lyase recorded a steady increase although the concentration of Al. Not only a single fraction of polyamine was responsible under Al stress but also pool of conjugated polyamine was up regulated. In oxidation of polyamine the activity of diamine oxidase (DAO) was more under metal stress to induce accumulation H2O2. In compensation for cellular depletion of reduced glutathione, dihydro ascorbate reductase activity was up regulated in plant under stress. At cellular level plants were distinctly marked with variations in heat shock proteins and established as a possible biomarker for Al toxicity. The study possibly established the affectivity in bio-monitoring of Al in field condition with exercise cellular responses of Salvinia plants.

Study on the relationships between yield and its components will improve the efficiency of breeding programmes by determining appropriate selection criteria. An investigation was carried out on 24 potato genotypes to find out the association among yield, yield components and their direct and indirect effects on tuber yield of potato. The experiment was laid out in randomized complete block design with three replications at Sinana Agricultural Research Center. The association was analyzed by correlation coefficient, and further subjected to path analysis to estimate direct and indirect effects of each character on tuber yield. Positive and significant genotypic and phenotypic correlation were found between total tuber yield and marketable tuber yield (rg=0.99), leaf area index (rg=0.82), plant height(rg=0.56), stem number per plant(rg=0.56), average tuber weight (rg=0.74) and biomass yield (rg=0.69). Path analysis of tuber yield and its components shows that marketable tuber yield and average tuber weight had maximum positive direct genotypic and phenotypic effect on total tuber yield indicating their importance in selection for tuber yield improvement.

Moving beyond seed storage in tackling plant loss: linking seed collection and re-introduction
Jaganathan, Ganesh K.
University of Shanghai for Science and Technology
Liu, Bao-lin
University of Shanghai for Science and Technology
Globally, plants are becoming extinct at an unprecedented rate. Seed banking is considered as the most cost-effective technique to preserve many conservation concern species. From a practical standpoint, however, banking seeds is essentially just the first step in tackling plant loss, as the real-life challenge lies in how well these seeds when re-introduced become whole plants and maintain species count. In the current model, merely very few seed banks extend their efforts in re-introduction problems. Compelling evidence suggests that many re-introduction efforts are less than successful. Such axiom convicts seed banks must also participate in the ‘post-storage’ process and engage working with other ecologists, physiologists and re-introduction practitioners to devise a robust re-introduction practice and exchange information about the seed lot including collection site, maternal environment etc. Bridging these gaps would facilitate enhanced restoration practice and pave way for efficient reconstruction of the ecosystem.

Simple sequence repeats (SSRs) consist of short repeat motifs of 1-6 nucleotides and are found in DNA sequences.The present study was conducted to detect SSRs in chloroplast genome of Tetraphis pellucida (Accession number: NC_024291), downloaded from the National Center for Biotechnology Information (NCBI). The sequence was mined with the help of MISA, a Perl script, to detect SSRs. The length of SSRs defined as ?12 for mono, di, tri and tetranucleotide, ?15 for pentanucleotide and ?18 for hexanucleotide repeats. In total, 41 perfect microsatellites were identified in 127.489 kb sequence mined. An average length of 13.56 bp was calculated for mined SSRs with a density of 1 SSR/3.04 kb. Depending on the repeat units, the length of SSRs ranged from 12 to 20 nt. Dinucleotides (14, 34.15%) were the most frequent repeat type, followed by tetranucleotides (10, 24.39%), trinucleotides (7, 17.07%), mononucleotides (6, 14.63%) and pentanucleotide (4, 9.76%) repeats. Hexanucleotide repeats were completely absent in chloroplast genome of Tetraphis pellucida. The mined SSRs can be used to develop molecular markers and genetic diversity studies in Tetraphis species.

The liverwort diversity in Gujarat has been mostly neglected by biodiversity researchers across the state and more than 75% of the districts have never been investigated for their bryo-diversity. A detailed study was conducted during 2013-2015 covering 75 locations spread over 31 of the 33 district of the state to understand the diversity and distribution of liverworts in the state. The liverwort diversity in the state now stands at 22 species of which 16 species were located in the current study. Genus Riccia has the maximum diversity in the state. Cyathodium cavernarum Kunze. was the most widely distributed species being located in 17 out of the 31 districts studied. Taxilejeunea ghatensis, Riccia crystallina and R. cavernosa are new records to the state. Genus Marchantia is also being reported for the first time. Dangs and Panchmahal districts have the highest liverwort diversity with 10 species each.

Diversity & Distribution of Tropical Macrolichens in Shettihalli Wildlife Sanctuary, Western Ghats, Southern India
Vinayaka, K S
Department of Botany, Kumadvathi First Grade College, Shikaripura, Shimoga-577427, Karnataka
A total of 58 species of lichens were documented from the present study area, which is located between 13°40? and 14°05? N to 75°10? and 75°35? E longitude with wide range of ecosystem diversity at Shettihalli wildlife sanctuary, Shimoga district of Karnataka, India. We have surveyed a total area of 396 sq km which supports for 41 genera of lichens from 22 families. Some important lichen genera of the areas are Ramalina, Usnea, Heteroderma, Parmotrema etc. Corticolous lichens were found to be dominated in abundance, represented by 86%. Crustose lichens were represented by 54 species followed by foliose (43) and fruticose (14) species. The present investigations showed that the deciduous forests support a good macrolichen community’s diversity then the semi-evergreen forests in nearby area. An interesting observation made in the area is that fruticose lichens were restricted to branches of the tree and main trunk was dominated by foliose lichens. Important host trees which support the growth and distribution of lichens in the area are Tectona grandis, Terminalia spp., Adina cordifolia, Hopea spp., and Xylia xylocarpa

In the present study, a review of previously published literature regarding Anthocerophyta and Marchantiophyta of Pakistan and Kashmir has been done in order to know the diversity of these groups. Previous contributions collectively reveal 122 taxa distributed in 36 genera and 24 families. Of these 118 taxa (97.52%) are belonging to the Marchantiophyta, while the rest of 4 species (3.30%) members to Anthocerophyta. Aytoniaceae is the largest family with 16 species. Genera-wise, Riccia is the largest genus with 12 species. An average number of species/genera is c. 3.36. A major portion of Pakistan is still un-explored especially Sindh and Balochistan province of Pakistan, and on the basis of this study it can be said that many more taxa will be added to the list.
