Expression of a bacterial phaseolotoxin-resistant ornithyl transcarbamylase in transgenic tobacco confers resistance to Pseudomonas syringae pv. Phaseolicola

Toxins have been shown to be an important virulence component for most pathovars of Pseudomonas syringae . Here we have examined the role of phaseolotoxin in the virulence mechanism of P. syringae pv. phaseolicola by producing transgenic tobacco plants that express a pathogen–derived toxin–resistant...

Description
Summary:Toxins have been shown to be an important virulence component for most pathovars of Pseudomonas syringae . Here we have examined the role of phaseolotoxin in the virulence mechanism of P. syringae pv. phaseolicola by producing transgenic tobacco plants that express a pathogen–derived toxin–resistant target enzyme. Such plants are insensitive to the toxin and less prone to infection by the pathogen.
