摘　　要：miR159(microRNA159)是植物中一类古老而又保守的microRNA,其靶基因主要是一类编码R2R3 MYB转录因子的GAMYB-like基因。miR159-GAMYB途径高度保守,miR159通过转录后调控GAMYB在植物营养生长、开花诱导、雄性生殖、花器官发育、植物育性、果实发育、种子萌发和胁迫响应中发挥着重要作用。主要探讨了近些年来miR159-GAMYB途径对植物生长发育的影响,为今后相关研究提供参考。miR159(microRNA159)is an ancient and conserved microRNA in plants,which targets a class of regulatory genes called GAMYB-like that encode R2R3 MYB transcription factors.miR159-GAMYB pathway is highly conserved,miR159 plays a critical role in vegetative growth,flowering induction,male reproduction,floral organ development,plant fertility,fruit development,seed sprouting and stress response by the post-transcriptional regulation of GAMYB.The article mainly discusses the influence of miR159-GAMYB pathway regulating plants growth and development,which provides a reference for future related researches.
