Abstract

Exon junction complexes (EJCs) associate with mRNAs, mediate the pre-mRNA splicing and eventually gets displaced by ribosomes during the initial phase of translation. EJCs are involved in several critical physiological pathways. The functional nature of EJCs and the underlying molecular mechanism(s) still needs to be elucidated particularly in case of plants. Here, we report that the putative core protein factors of the EJC differentially express under short-day and long-day conditions. Since, plants are constantly exposed to biotic and abiotic factor(s), it would be significant to see how the EJCs respond to different stress inducing conditions. The protein levels of EJC core proteins under short-day conditions were 1.25 times higher relative to the protein levels under long-day conditions. Similar results were observed for the mRNA transcripts of the EJC core protein factors. These results signify that under short-day conditions, the EJC proteins are more activated and might be involved in few events which are yet to be revealed.
