摘　　要：microRNA(miRNA)是一种含20-25个核苷酸的内源性非编码RNA,并在植物体内广泛存在。miRNA主要在转录后水平发挥作用,通过负向调节植物基因的表达,从而参与调控植物的生长发育、胁迫响应以及激素信号转导等过程。本文从miRNA的产生、作用方式出发,阐述其在胁迫响应过程中的作用机制,旨在更加深入的了解miRNA在胁迫响应过程中的分子调控网络,以期为未来利用基因工程手段提高植物抗逆性提供参考性作用。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.
