A bacterial E3 ubiquitin ligase targets a host protein kinase to disrupt plant immunity

Article Abstract:

AvrPtoB, a type III effector contains an E3 ubiquitin ligase that targets a host protein kinase, Fen to disrupt and damage the immunity of a plant. Fen physically interacts with the effector and activates the plant immune system, hence providing it a highly conserved host resistance mechanism.
