摘　　要：植物信号肽的研究主要集中在小分子肽。小分子肽作为胞间通讯的关键成分,主要参与信号干扰、反应途径、显示抗菌活性,并以配体的形式与细胞膜表面的受体激酶相互作用,从而实现细胞之间的信号交流。小分子肽是重要的胞间信号感应分子,在植物的不同器官组织、发育阶段主要参与调节植物的生长发育过程和应答生物和非生物胁迫的应激反应,以协调和整合细胞功能。该文全面概述了植物小分子肽的发现、结构特点、分类系统及其功能研究进展,并重点对近年来国内外有关翻译后修饰小肽CLE(CLAVATA3/ESR)家族和富含半胱氨酸肽RALF(快速碱化因子)家族的研究进展进行综述,为植物小分子肽的深入研究提供基础信息,并为今后的研究方向提供参考。The research of plant signal peptides mainly focuses on small molecular peptides.As a key component of intercellular communication,small molecular peptides are mainly involved in signal interference,response pathways,display antimicrobial activity,and interaction with receptor kinases on the surface of cell membranes in the form of ligands,which are enable signal communication between cells.Small peptide molecules are important intercellular signal sensing molecules that are critically involved in regulating growth and development processes and stress responses in response to biotic and abiotic stresses in different organ tissues and developmental stages of plants to coordinate and integrate cellular functions.This review indicates a comprehensive overview of the discovery,structural features,classification system,and functional progress of plant small molecule peptides,and focuses on recent years at home and abroad on the CLE(clavata3/ESR)family of post-translational small peptides and Ralf(rapid alkalinization factor)family of cysteine rich peptides,provides basic information for in-depth studies of plant small molecule peptides and reference for future research directions.
