摘要: MicroRNAs(miRNAs)是一类内源性小分子的非编码RNA,它通过对其靶基因mRNA的降解或抑制翻译来调控基因表达,进而参与调控植物相关生理活动。在逆境胁迫下,植物中的一些miRNA通过迅速表达并作用于某些与逆境相关的基因,以启动植物的某些抗逆信号系统,进而提高植物对不良环境的适应能力。就miRNA的产生、作用方式、研究方法及其在植物在逆境胁迫中的抗逆作用机制研究进行了综述,并对植物miRNA的研究发展趋势进行了展望。

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.
