UNL Researchers Identify Target of Disease-Causing Plant Pathogens

A team of University of Nebraska-Lincoln researchers led by Jim Alfano at the Center for Plant Science Innovation and Department of Plant Pathology have published their findings into the work of the bacterial pathogens that target a plant’s immune system. Their study centered on the pathogen Pseudomonas syringae and its method of injecting the protein HopE1 into plant cells which through a series of reactions ultimately compromises the plant’s immune system.

The research into HopE1 is part of the team’s larger work to identify new components in plant immunity. An improved understanding of the defense mechanisms of plants would pave the way to improved disease resistance of crops and therefore increase crop quality and yield.
