Identification of Pseudomonas syringae genes required for perception of host-derived virulence-inducing metabolites

Creator:: Turner, Sydney E.
Abstract:: Pseudomonas syringae is a Gram-negative bacterium that can infect a variety of important crops. Infection by P. syringae is dependent on a type III secretion system (T3SS) that delivers effector proteins to plant cells to suppress host defenses. Previous work has shown that, in the presence of simple sugars, specific...
