摘　　要：植物凝集素类受体激酶(lectin receptor-like kinases, LecRLKs),隶属于植物膜蛋白类受体激酶,LecRLKs主要由胞外凝集素结构域、跨膜结构域和胞内激酶结构域组成,根据胞外结构域的特异性,分为G型、L型和C型,凝集素类受体激酶参与植物的生长发育和环境响应调控。该文总结凝集素类受体激酶的研究历史、结构和分类,阐述植物LecRLKs的发育调控和胁迫响应功能,对功能明确的LecRLKs基因进行归类。提出凝集素类受体激酶研究中存在的不足之处,包括该家族演化历史研究极其缺乏、信号传导途径及其潜在配体亟待开展等方面。在此基础上,提出未来深入研究的方向,以期为植物凝集素类受体激酶基因家族的定向育种提供理论支持。Plant lectin receptor-like kinases(LecRLKs),which belong to the family of plant receptor-like kinases,are a group of plant membrane protein receptors.LecRLKs are primarily composed of extracellular lectin domains,transmembrane domains,and intracellular kinase domains.They can be classified into G-type,L-type,and C-type based on the specificity of their extracellular domains.In plants,lectin receptor-like kinases play a significant role in regulating growth,development,and environmental responses.This article provides a comprehensive review of the research history,structure,and classification of lectin receptor-like kinases,systematical elucidation of their critical functions in plant growth,development,and responses to environmental stimuli,and categorization of genes with established functions.The article also discusses the limitations in previous lectin receptor-like kinase researches,including the lack of evolutionary history elucidation,unclear signal pathways,and unidentified ligands.Based on the current state of researches,the specific recommendations are proposed with the aim of providing theoretical support for targeted breeding within the gene family.
