摘　　要：逆境胁迫是植物生长发育过程中常见的生物学现象,为适应不同环境条件,植物会通过一系列的逆境响应机制来维持生命活动。近年来,研究表明microRNA在逆境胁迫响应中发挥着重要的作用。本文综述了microRNA的合成及作用机制,研究microRNA的常用方法以及microRNA在温度、水分、盐、重金属等逆境胁迫条件下的响应机制,对于深入理解植物响应逆境胁迫具有重要意义。Stress is a common biological phenomenon in plant growth and development.To adapt to different environmental conditions,plants maintain their life activities through a series of stress response mechanisms.In recent years,research has shown that microRNA plays an important role in response to stress.This article reviews the synthesis and mechanism of action of microRNA,common methods for studying microRNA,and the response mechanism of microRNA under stress conditions such as temperature,water,salt,and heavy metals.It is of great significance for a deeper understanding of plant response to stress.
