“Listening In” on How a Bacterium Takes Over the Plant Vascular System
ABSTRACT Bacteria that infect the plant vascular system are among the most destructive kind of plant pathogens because pathogen proliferation in the vascular system will sooner or later shut down the plant’s water and nutrient supply and necessarily lead to wilting and, in the worst case, death of t...

ABSTRACT Bacteria that infect the plant vascular system are among the most destructive kind of plant pathogens because pathogen proliferation in the vascular system will sooner or later shut down the plant’s water and nutrient supply and necessarily lead to wilting and, in the worst case, death of the entire plant.
