Role of RNA binding Proteins (RBPs) in response to abiotic stress in plants


Proteins accompany RNA molecules from cradle to grave. In eukaryotes, RNA-binding proteins participate in synthesizing, processing, editing, modifying and exporting RNA molecules from the nucleus. They carry RNA molecules between cells and to their destinations within cells. They are involved in all aspects of translating mRNAs, as well as regulating the stability of mRNA and degrade it. Mechanistically, each of these events is regulated by the formation of different ribonucleoprotein (RNP) complexes with RNA-binding proteins (RBPs) at their core. Although relatively few plant RNA-binding proteins have been characterised genetically and biochemically, presence of more than 250 RBDs in Arabidopsis and rice suggest that they might serve specific plant function. Besides their role in normal cellular functions, RBPs are also emerging as an important class of proteins which provide plants the ability to respond rapidly against environmental stress. Several evidences support the role of RBPs in plant adaptation to various unfavourable environmental condition and their contribution to enhance plant tolerance to abiotic stress.
