Xylella fastidiosa requires the Type II secretion system for pathogenicity and survival in grapevine.

Molecular Plant-Microbe Interactions, 2023
Xylella fastidiosa is a xylem-limited bacterial pathogen that causes Pierce's Disease (PD) of grapevine. In host plants, this bacterium exclusively colonizes the xylem, a tissue that is primarily non-living at maturity. Understanding how X.
