| 摘 要： | 植物中的小RNA参与多种生物学过程,依据其起源及前体结构的不同主要分为两类:微小RNA(miRNAs)和小干扰RNA(siRNAs),它们的长度通常为21~24个核苷酸,在生物合成途径以及作用机制等方面存在差异。病原物侵染植物后常通过诱导或抑制小RNA分子来调节抗病相关基因的表达,进而调控植物与病原物的互作反应。文章就小RNA的生物合成、作用途径及其在植物与病原物互作中的调控机制等方面进行了综述。

| Abstract: | Small RNAs are involved in a multitude of biological processes in plants. Based on their origins and precursor structures, small RNAs can be divided into two major classes: microRNAs (miRNAs) and small interference RNAs (siRNAs). Small RNAs are typically 21-24 nucleotide (nt) long, and differ in both biogenesis and biological function. In the pathogenic process, pathogens can either induce or suppress the synthesis of small RNAs, which, in turn, regulate the expression of pathogenesis-related genes to mediate diverse plant-pathogen interactions. The biogenesis and biological functions of small RNAs, together with possible regulation mechanisms underlying the host-pathogen interactions, are summarized in this review. |
