A proposed model of action for demonstrating regulatory function of PbrWRKY53 in response to drought stress. The ABA signalling pathway is triggered by drought stress, leading to enhancing the expression levels of PbrWRKY53, which in turn regulates PbrNCED1 through binding to W‐box element in its promoter. Up‐regulation of the PbrWRKY53‐PbrNCED1 module promotes AsA synthesis and ROS scavenging, allowing the drought‐associated damage to be alleviated by maintaining ROS homeostasis and adjustment of stomatal aperture.
