a
P. syringae pv. glycinea data are from Ferris et al. (5), and data for P. pseudoalcaligenes East River isolate A (ERA) were from Ford et al. (24). P. syringae pv. atrofaciens and P. syringae pv. glycinea are closely related to the original host P. syringae pv. phaseolicola while P. pseudoalcaligenes East River isolate A is distantly related to the original host.
b
n, total number of wild-type isolates studied.
