This study characterizes PUB33, an Arabidopsis RLCK-IXb/PUB-VI protein, showing it has dual kinase and E3 ubiquitin ligase activities regulated by autophosphorylation and interacts with the bacterial effector RipV1 to modulate immune responses.

This study shows that phosphorylation of Exo70B2 regulates its function in secretion and immunity by modulating its localization and interaction with the secretory pathway.

The paper investigates HvARM1, a partial gene duplicate of HvPUB15 in barley, showing its role in resistance to powdery mildew fungi and its interaction with plastid proteins.
