Leucine-rich repeat receptor-like kinases (LRR-RLKs) are integral to the adaptive mechanisms employed by plants during biotic and abiotic stresses. With global climate change, drought has become a menacing abiotic factor for plant growth and survival. It is well-known that plasma membrane-anchored LRR-RLKs show complicated actions in regulating the interlinking between abscisic acid (ABA) and brassinosteroid (BR) signaling, stomatal movement, and ROS (reactive oxygen species) homeostasis through the phosphorylation of target proteins in response to drought stress. In this review, we provide a comprehensive summary of the mechanisms by which LRR-RLKs in plants confer regulatory responses under a water-limited environment, which hopefully offers valuable information for future crop germplasm improvement with drought tolerance.
富含亮氨酸重复序列的类受体蛋白激酶（LRR-RLKs）在植物应对生物和非生物胁迫时所采用的适应性机制中不可或缺。随着全球气候变化，干旱已成为威胁植物生长和生存的非生物因素。众所周知，质膜锚定的LRR-RLKs在响应干旱胁迫时，通过对靶蛋白进行磷酸化作用，在调节脱落酸（ABA）和油菜素内酯（BR）信号传导、气孔运动以及活性氧（ROS）稳态之间的相互联系方面表现出复杂的作用。在本综述中，我们全面总结了植物中LRR-RLKs在水分受限环境下赋予调节反应的机制，希望能为未来耐旱作物种质改良提供有价值的信息。
