The paper identifies Xanthomonas euvesicatoria effectors recognized by Solanum americanum immune receptors, showing their role in effector-triggered immunity and bacterial infection.

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 identifies 12 YopJ family effectors recognized by NbZAR1 or NbPtr1 in N. benthamiana and shows differential suppression of HR by a deacetylase.

This study identifies RLCK-IXb proteins as targets of the Ralstonia solanacearum effector RipV1, revealing their role as negative regulators of plant immunity.

This study identifies how the bacterial effector RipE1 stabilizes by hijacking plant ubiquitin proteases and phosphorylation, avoiding degradation and promoting bacterial survival.
