Total plasmid DNA was successfully isolated from 46 of 55 strains of Pseudomonas syringae . Electrophoretic separation after digestion with restriction endonuclease Eco RI gave reproducible banding patterns. Cluster analysis of banding data grouped all strains of pathovar (pv.) pisi separately from pv. glycinea , pv. phaseolicola and pv. syringae . Pathovars glycinea and phaseolicola were more similar to each other than to pv. pisi. A relationship between fragment banding patterns and race structure within pv. pisi was observed.
