Research Progress of microRNAs in Plant Stress Responses

doi:10.13560/j.cnki.biotech.bull.1985.2021-1345

Abstract

Abstract:

microRNAs（miRNAs）,endogenous non-coding RNAs containing 20-25 nucleotides,exist widely in plants. miRNAs mainly play roles at the post-transcriptional level by negatively regulating the expressions of plant genes,thereby participating in the regulation of plant growth and development,stress response,and hormone signal transduction processes. This article summarizes the current progresses on the generations and functions of miRNA,mainly focusing on their roles in the stress response,aiming to have a deeper understanding of the molecular regulatory network of miRNA in the stress response process,and to provide a reference for improving plant stress resistance through genetic engineering in the future.

Key words: miRNA, stress response, regulation, target gene
