Tetraphis
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.

Liverwort
Gujarat
Diversity
Riccia
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.

Macrolichens
Tropical lichens
Shettihali
Parmotrema
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

Molecular Genetics
Transformation
The liverwort, Marchantia polymorpha L., one of the species of first land plants is a promising model plant system for the analysis of diverse facets of contemporary plant biology. The unique characteristics of the plant such as dominant haploid gametophytic generation enables the isolation and disruption of mutant for genetic analysis, rapid sexual and asexual reproduction can be induced under controlled conditions which leads to the formation of genetically homogenous lines and also the complete organelle genome sequence of chloroplast and mitochondria has been established. In addition, the ongoing whole genome sequencing of M. polymorpha by the community sequencing plan at the Joint Genome Institute specifies the conservation of several mechanisms of biological science that are instituted in other terrestrial plants in a smaller extent of intricacy. Thus, with the development of several feasible and reliable genetic transformation strategies, in vitro cell culture, gene silencing, targeted gene modification and its critical evolutionary position make this plant as a potential model plant to study evolutionary and developmental biology in detail.

Eastern Ghats
Odisha
Similipal
In an attempt to reveal the biodiversity status of one of the least studied plant groups of Eastern Ghats, the authors have catalogued the diversity and distribution of bryoflora of Odisha situated in the Northern Eastern Ghats biogeographic regions of India. One hundred fourty nine species of bryophytes including 102 mosses under 23 families, 41 liverworts under 16 families and 6 hornworts under 2 families were reported from Odihsa as a result of 7 years of primary survey (2008-2015) conducted in some selected bryodiversity rich habitats covering 12 districts of Odisha and also from scrutiny of different research publications including research papers, books and research reports. In terms of species richness, the Deomali hills was found to be the most diverse in terms of bryophytes followed by Similipal biosphere reserve, Mahendragiri hills, Niyamgiri hills, Baphlimali hills and Khandadhar hills. Deomali hills also showed highest diversity in endemic mosses. Five mosses such as Fissidens orishae Gangulee, Erpodium mangiferae Müll. Hal., Hyophila comosa Dixon, Stereophyllum confusum Ther., Neckeropsis exserta (Hook. ex Schwagr.) Broth. are found to be endemic to India that occur in Odisha. Aneura pinguis (L.) Dumort., Anoectangium stracheyanum Mitt., Cyathophorella hookeriana (Griff.) M. Fleisch., Cyathophorum adiantum (Griff.) Mitt., Distichophyllum schmidtii Broth., Eurhynchium striatulum (Spruce) Schimp., Hypnum cupressiforme Hedw., Leucobryum juniperoideum (Brid.) Müll. Hal., Lophocolea bidentata (L.) Dumort., Macromitrium sulcatum (Hook.) Brid., Notothylas levieri Schiffner, Pallavicinia lyellii (Hook.) Gray Pellia epiphylla (L.) Corda., Philonotis fontana (Hedw.) Brid., Pogonatum neesii (Müll. Hal.) Dozy., Polytrichum commune Hedw., Polytrichum juniperinum Hedw., Racopilum cuspidigerum (Schwagr.) Angstrom, Racopilum orthocarpum Wilson ex Mitt., Riccia beyrichiana Hampe ex Lehm., Riccia billardieri Mont. & Nees., Spruceanthus semirepandus (Nees) Verd., Thuidium cymbifolium (Müll. Hal.) Paris, Thuidium koelzii H. Rob., Trematodon longicollis Michx., are some of the new distributional record of occurrence for the Eastern Ghats.The present study reveals that Fissidentaceae, Pottiaceae, Bryaceae, Dicranaceae, Aytoniaceae, Marchantiaceae, Funariaceae and Anthocerotaceae are dominant families in the study area. The authors have also identified few forest pockets and critical habitat in the state where bryophyte diversity shall be very rich that needs a detailed survey in near future. The authors discuss the list of bryophytes of the state in a regional context of rarity, as well as address some general subject matters regarding cryptogam conservation and further work needed in the state of Odisha. The study would provide a prelude data for future bryological studies and bryomonitoring in the Eastern Ghats in general and the state of Odisha in particular.
