Role of MicroRNAs in Biotic and Abiotic Stress Tolerance in Plants

Abstract

Shweta Tripathi* and Pratyusha Bose

MicroRNAs or miRNAs are small non-coding RNAs which are important regulators of various developmental and survival processes of the eukaryotic organisms. They regulate the expression of genes post-transcriptionally. Upregulation or downregulation of miRNA expression leads to alteration of many signalling and developmental processes which can help or harm the organism. Plants are no exception to that. In the last 30 years many miRNAs have been found to be deregulated under various abiotic and biotic stresses in plants and also to be closely associated in tolerance of the same. This review focuses on the involvement of miRNAs in stress tolerance in plants that have been identified so far.
