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
