A mini-review on the role of leucine-rich repeat receptor-like kinases (LRR-RLKs) in plant responses to drought stress
摘要
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.
