Sequence variations in alleles of the avirulence gene avrPphE.R2 from Pseudomonas syringae pv. phaseolicola lead to loss of recognition of the AvrPphE protein within bean cells and a gain in cultivar-specific virulence.

Abstract excerpt
The bean halo blight pathogen, Pseudomonas syringae pv. phaseolicola (Psph), is differentiated into nine races based on the presence or absence of five avirulence (avr) genes in the bacterium, which interact with corresponding resistance genes. R1-R5, in Phaseolus vulgaris. The resistance gene R2...
