中文摘要：

植物miRNAs是广泛分布于植物基因组的非编码小分子RNA,主要在转录后通过介导靶mRNA降解或翻译抑制来调控基因的表达水平,从而影响植物器官发生和发育。该研究综述了植物miRNA生物发生过程及其作用机制,并重点阐述了miRNAs在植物器官发育的作用,以期为尽快全面揭示植物器官发育调控机理提供理论依据。

英文摘要：

Plant miRNAs are small non-coding RNAs which widely exist in plant genomes,and mainly regulate gene expression in the post-transcriptional level by guiding the cleavages or attenuating the translation of target gene,and thus affect plant organ and development.This review provided a summary of the biogenesis and action mechanism of plant miRNAs,and discussed the role of miRNAs families that had been involved in the control of plant organ development,and provided theoretical basis for revealing the regulatory mechanism of plant organ development comprehensively as soon as possible.
