摘要/Abstract

摘要： 类受体激酶（receptor-like kinase,RLK）是植物体内普遍存在的一类蛋白激酶,是许多信号识别传递途径中的关键组分,作为识别信号的质膜受体,能够感受外界刺激,通过磷酸化作用参与胞内信号传递。富含半胱氨酸的类受体激酶（cysteine-rich receptor-like kinase,CRK）又被称为DUF26（domain of unknown function 26）类受体激酶,是RLK中的一大类。近几年,越来越多的研究发现CRK参与了植物的抗病防御反应。综述了植物CRK蛋白的结构特征,总结了目前已发现的CRK在生物胁迫、非生物胁迫及生长发育中的功能,并对CRK未来的研究进行了展望,旨为后续阐明CRK的功能和分子机制提供参考。

Abstract: Receptor-like kinases（RLKs）are protein kinases existing in plants,and play an essential role in many plant signal transduction pathways. As receptors localized on plasma membrane,RLKs perceive environmental stimuli and are involved in intercellular signal transductions through phosphorylation. Cysteine-rich receptor-like kinases（CRKs）,also called domain of unknown function 26（DUF26）receptor-like kinases,are a large subgroup of RLKs. Recently,CRKs are found to be involved in plant disease resistant defenses. In this paper,we reviewed the structural characters of CRKs and summarized biological functions in abiotic and biotic stresses and their roles in plant growth and development,moreover,we prospect the future research,aim to follow-up stuclies.

Key words: cysteine-rich receptor-like kinases, abiotic stress, biotic stress, biological functions
