摘　　要：富含甘氨酸蛋白(glycine-rich proteins,GRPs)是一类序列中含有甘氨酸高度重复序列的蛋白家族,植物GRPs家族成员众多,其功能丰富多样。目前的研究表明,GRPs在植物生长发育以及对环境因子的响应中具有重要作用。早在1986年在植物中分离鉴定了第一个GRP基因,近年来有关GRPs参与植物生长发育与逆境响应的研究取得了显著进展,丰富了人们对GRPs功能的认识,但国内仍缺少对植物GRPs功能的系统总结。为此,本文系统总结了GRPs家族蛋白的序列结构特征、家族分类、亚细胞定位特性以及它们在植物生长发育与逆境胁迫调控中的最新研究进展。根据序列结构的差异,植物GRPs家族可分为五大类,第Ⅳ类的GRPs又可分为4个亚家族。植物GRPs家族基因的表达具有明显的组织特异性和发育阶段特异性,同时还受多种环境因素的调控。GRPs不仅是细胞结构的重要组分,还广泛参与植物正常和逆境环境下的生物学过程,在逆境条件下可能还具有一定的跨细胞器穿梭能力。通过本文的系统总结,期望能为国内相关领域的研究提供参考和借鉴,推动国内对植物GRPs功能的研究向更高水平前进,并为后续研究提供可借鉴的思路和方向。Glycine-rich proteins(GRPs)are a superfamily of proteins distinguished by their semi-repetitive glycine-rich sequences.Plant GRPs have many members and serve a variety of essential functions.The current researches show that plant GRPs play critical roles in plant growth and development,and respond to environmental factors.The first GRP gene was isolated and identified in plants as early as 1986.In recent years,significant advancements have been made in understanding the roles of GRPs in plant growth and development,and stress responses,thereby enriching our knowledge on their functions.However,there remains a lack of systematic reviews regarding the functions of plant GRPs in the domestic literature.Therefore,this article systematically summarizes the structural characteristics,family classification,and subcellular localization of the plant GRPs family,along with the latest research on their roles in plant growth and development,and stress regulation.Based on the variations in sequence structure,the plant GRPs were categorized into five major groups,with theⅣcategory could further divide into four subfamilies.The expression of GRP genes shows significant tissue specificity and developmental stage specificity,also is adjusted by various environmental factors.GRPs serve not only as crucial components of cellular structure,but are also actively involved in biological processes under both normal and stressful conditions.Moreover,they may possess certain cross-organelle shuttle capabilities when faced with adverse stresses.Through the comprehensive review,the article aims to provide valuable insights and references for studies in related fields in China,thereby advancing the study of plant GRPs and offering guidance for future research directions.
