Abstract: MicroRNA(miRNAs)is a class of endogenous non-coding small RNAs, which participate in regulation of physiological activities by target mRNA cleavage or translational repression in plants. Some miRNAs play important roles in stress-related signal transduction and improving resilience against adverse environmental hazards of plant capacity by regulating gene expression under stressed conditions. This article focused on the production of miRNA, mechanism, research approaches and characteristics of resisting the biotic and abiotic stresses in plants, the development trends and future prospect of plant miRNAs research.

Key words: microRNA, stress, bioinformatics, target gene, gene regulation
