Abstract

RNA-binding proteins (RBPs) in eukaryotes have crucial roles in all aspects of post-transcriptional gene regulation. They are important governors of diverse developmental processes by modulating expression of specific transcripts. The Arabidopsis (Arabidopsis thaliana) genome encodes for more than 200 different RBPs, most of which are plant specific and are therefore likely to perform plant-specific functions. Indeed, recent identification and analysis of plant RBPs clearly showed that, in addition to the important role in diverse developmental processes, they are also involved in adaptation of plants to various environmental conditions. Clearly, they act by regulating pre-mRNA splicing, polyadenylation, RNA stability and RNA export, as well as by influencing chromatin modification.
