摘要: microRNAs(miRNAs)是一类长度为19-25 nt的非编码小分子RNA,在转录后水平调控植物的生长发育、信号传导及逆境响应等多个过程,现已成为生物学研究的热点。miR172是植物中一个保守的miRNA家族,通过调控APETALA2类基因,在植物的开花诱导、花器官形态建成、果实成熟、叶片和根的生长等各器官的发育过程中起到重要作用。鉴于此,综述了近20年miR172在植物营养器官、生殖器官及其他器官的发育,以及在发育阶段过渡中的功能,讨论了其他因素对miR172的影响,以期为深入解析miR172及其靶基因的作用机理和分子调控网络提供参考。

Abstract: microRNAs(miRNAs)are a class of non-coding small molecular RNA with a length of 19-25 nt regulating the growth and development of plants,signal transduction and stress response at the post-transcriptional level,which has become the hotspot in biology. miR172,a conserved miRNA family in plants,plays an important role in the development of various organs in plants,such as flowering induction,flower organ morphic formation,fruit maturation,and leaf and root growth,through the regulation of APETALA2 genes. In view of this,this paper reviews the development of miR172 in vegetative organs,reproductive organs and other organs of plants in the past 20 years,as well as its functions in the transition of development process,and discusses the effects of other factors on miR172,so as to provide references for the in-depth analysis of the action mechanism and molecular regulatory network of miR172 and its target genes.

Key words: miR172, plant development, vegetative organs, reproductive organs, morphogenesis
