植物M/MLD类受体蛋白激酶及其生物学功能的研究进展

Research Progress on Plant M/MLD-RLKs and Their Biological Functions

植物受体蛋白激酶通过与胞外信号结合感知和接收外部信号传递,在植物各个生理过程及生物代谢中发挥着重大的作用。其中M/MLD类受体蛋白激酶是一类植物特有的具有Malectin-like结构域的受体蛋白激酶。研究表明,M/MLD-RLKs亚家族参与植物发育过程及生物/非生物胁迫调控。该研究对近年来国内外有关植物M/MLD-RLKs的发现、结构特点以及生物学功能等方面的研究进展进行综述,并重点阐述其在调控植物根系、叶片、花发育及响应多种胁迫过程中的作用,为深入研究M/MLD-RLKs在植物生长发育过程中的生理功能提供参考。

Plants have evolved large families of receptor-like kinases(RLK)to perceive and process external signal to form coordinated responses,which are critical to adapt to various physiological processes and biological metabolism of plants.M/MLD-RLKs are unique to plants because of their unique and novel malectin-like domains in their extracellular domain.Recent studies have shown that M/MLD-RLKs involved in plant development and biotic/abiotic stress regulation.This article reviews the research history,structural characteristics and biological functions of plant M/MLD-RLKs.We systematically reviewed the recent studies on the functions of M/MLD-RLKs in regulating plant roots,leaves,flower development and various stress responses.This will provide a reference for elucidating the physiological functions of M/MLD-RLKs in the process of plant growth and development.
