Genomic Fingerprinting of Two Pathovars of Phytopathogenic Bacteria by Rare-Cutting Restriction Enzymes and Field Inversion Gel Electrophoresis

We examined 10 strains of P.s. tomato and identified two groups that could be readily distinguished from each other. Strains of other pathovars of P. syringae had genomic fingerprints very different from those of the strains of P. s. tomato. The strains of X. c. vesicatoria all had similar genomic fingerprints, but distinctive subgroups within the pathovar could be identified. Strains of other pathovars of X. campestris also had very different genomic fingerprints from the strains of X. c. vesicatoria
