Abstract

CS-18-3 - Introducing 'PSYTEC': A Pseudomonas syringae Type III Effector Compendium for Plant-Microbe Interaction Research

Monday, July 16
3:58 PM - 4:18 PM

The type III secretion system is a crucial virulence apparatus of the plant pathogen Pseudomonas syringae. The type III effectors delivered by this system can either promote pathogenesis on susceptible host plants or activate an effector-triggered immune response on resistant plants. P. syringae is subdivided into host-restricted isolates termed pathovars, which each contain a unique repertoire of type III effectors that contribute to host specificity. Using the pan-genome of ~400 sequenced pathovars, we have generated a compendium of type III effectors (PSYTEC) that captures the sequence diversity of the P. syringae effectorome. PSYTEC consists of just over 70 families of type III effectors that can be subdivided into approximately 450 subgroups. We will present our preliminary functional characterization of PSYTEC and reveal its value as a powerful resource for dissecting crucial facets of plant-microbe interactions.
