Assessment of genetic diversity among strains of Pseudomonas syringae by PCR-restriction fragment length polymorphism analysis of rRNA operons with special emphasis on P. syringae pv. tomato.

Abstract excerpt

Phylogenetic relationships among 77 bacterial strains belonging to Pseudomonas syringae and Pseudomonas viridiflava species were assessed by analysis of the PCR-restriction fragment length polymorphism (RFLP) patterns of three DNA fragments corresponding to rrs and rrl genes and the internal transcribed spacer, ITS1. No difference among all strains in rrs and rrl genes was observed with 14 restriction enzymes,...
