植物凝集素类受体激酶参与抗病的研究进展

Research progress on lectin receptor-like kinases and their roles in mediation of plant disease resistance

凝集素类受体激酶(Lectin receptor-like kinases,LecRLKs)是类受体激酶(Receptor-like kinases,RLKs)的一个亚族。根据结构域的不同,凝集素类受体激酶可分为L、G和C等3种类型。在植物中,凝集素类受体激酶被报道参与生物/非生物胁迫响应和植物发育调控。近年来,越来越多的研究发现,凝集素类受体激酶参与由细菌、真菌以及食草性昆虫等所引起的植物抗病反应。本文概述了植物凝集素类受体激酶的分类及结构特点,并系统阐述了该类激酶在植物抗病方面的作用,旨在增进对植物凝集素类受体激酶参与抗病功能的了解,并为作物抗病育种提供理论依据。

Lectin receptor-like kinases(LecRLKs)are a subfamily of receptor-like kinases(RLKs).Based on structural differences in their domains,LecRLKs can be divided into three subclasses,namely L-,G-,and C-types.LecRLKs play a vital role in plant development and responses to biotic/abiotic stresses.Recent studies have identified an increasing number of LecRLKs implicated in plant disease resistance caused by bacteria,fungi,and herbivorous insects.In this review,we summarize the classification and structural features of LecRLKs,and systematically describe their functions in plant disease resistance.This review should not only help clarify the functions of LecRLKs in plant disease resistance,but also provide a theoretical basis for crop disease resistance breeding.
