摘　　要：凝集素类受体蛋白激酶(Lectin receptor-like kinases,LecRLKs)是高等植物中的一类类受体蛋白激酶(Receptor-like kinases,RLKs),具有参与植物生长发育及胁迫耐受等多种功能。LecRLKs在结构上主要包括胞外凝集素结构域、跨膜连接区及激酶结构域,根据胞外凝集素结构域的不同,LecRLKs可分为3种类型:G型、L型及C型。根据近年来的研究,发现LecRLK家族中存在能够参与植物种子萌发、株高、茎和叶片发育、花器官发育和生殖发育的基因,这表明LecRLK家族基因与植物发育过程存在密切的关系。该文综述了植物凝集素类受体蛋白激酶的结构与分类,重点讨论相关凝集素受体蛋白激酶在植物发育过程中的作用,旨在加深对凝集素类受体蛋白激酶在植物发育过程中所发挥作用的理解,并为农业生产和作物改良育种提供理论依据。Lectin receptor-like kinases(LecRLKs)are a subset of receptor-like kinases(RLKs)found in higher plants,playing diverse roles in plant growth,development,and stress response mechanisms.Structurally,LecRLKs are characterized by extracellular lectin domains,transmembrane segments,and kinase domains.Classifying LecRLKs based on the diversity of their lectin domains,they are divided into three distinct types:G-type,L-type,and C-type,each evolving independently within their respective subgroups.Recent studies have shed light on the involvement of LecRLK family genes in various plant developmental processes,such as seed germination,stature regulation,leaf and stem growth,organogenesis,and reproductive development.This underscores the intimate connection between LecRLKs and plant development.This article presents an overview of the structure and classification of lectin receptor-like kinases,emphasizing their pivotal roles in plant development.Through elucidating the functions of LecRLKs in plant growth processes,this review aims to enhance our comprehension of these kinases'contributions to plant development and offer a theoretical foundation for leveraging this knowledge in agricultural practices and crop enhancement programs.
