植物凝集素类受体激酶(lectin receptor-like kina.es， 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。
