Abstract Pathovars of Pseudomonas syringae cannot be differentiated merely by biochemical tests and O-antigen serological reactions. Envelope protein profiles were compared for strains of four P. syringae pathovars (pvs aptata, glycinea, pisi and syringae). Three protein bands of 60, 65 and 150 kDa were present in all of the 29 P. syringae pv. pisi strains studied, independent of their races, O-serogroups or biochemical characters. The three protein bands distinguished P. syringae pv. pisi from 29 P. syringae pv. syringae strains (absence of the bands), three pv. glycinea strains (absence of the 60 kDa protein), and three of four pv. aptata strains. Extraction conditions for the specific proteins were optimized, their localization in the envelope determined and their role discussed.
