Abstract excerpt

Both plant receptor-like protein kinases (RLKs) and ubiquitin-mediated proteolysis play crucial roles in plant responses to drought stress. However, the mechanism by which E3 ubiquitin ligases modulate RLKs is poorly understood. In this study, we showed that Arabidopsis PLANT U-BOX PROTEIN 11 (PUB11), an E3 ubiquitin ligase, negatively regulates abscisic acid (ABA)-mediated drought responses. PUB11 interacts with...
