摘要
miPEP(microRNA-encoded peptide)是由miRNA初级转录本(pri-miRNA)5'区域编码的微肽,能够与其编码序列小开放阅读框(miORF)相互作用以影响相关基因表达.miPEP外源处理植物能够增强pri-miR-NA表达,从而促进相应miRNA积累,抑制miRNA靶基因表达,在植物生长发育和抗逆性中发挥作用.因此,miPEP具有成为对环境友好的高效植物生长调节物质的潜力,以改善农艺性状.本文综述了miPEP的发生过程、外源miPEP的吸收与转运过程,概述了miPEP在植物中已发现的功能及作用机制.
Abstract
miPEP(microRNA-encoded peptide)is a micropeptide encoded by the 5'region of the primary miRNA transcript(pri-miRNA).It specifically interacts with its coding sequence,termed the micropeptide open reading frame(miORF),to regulate the expression of target genes.The external application of miPEP has been demonstrated to enhance the expression of pri-miRNA,contributing to increased accumulation of the corresponding miRNA.This process subsequently inhibits the expression of miRNA target genes,leading to modifications in plant phenotypic traits.miPEP plays a significant role in plant growth,develop-ment and resistance to abiotic stress.It has the potential to serve as an environmentally friendly and po-tent plant growth regulator that improves agronomic traits without relying on genetic approaches.In our review,the generation of miPEP,as well as the absorption and transport of exogenous miPEP were re-viewed.Additionally,the functions and mechanisms of miPEP identified in plants were summarized.
