title: Identification by replicon-typing of indigenous plasmids of Burkholderia (Pseudomonas) solanacearum.
abstract: Fifteen strains of Burkholderia (Pseudomonas) solanacearum were isolated, identified from different parts of India and screened for plasmid profile. They harboured 1-3 plasmids, but most of the isolates contained a single plasmid. Plasmids were classified on the basis of replicon typing by Southern hybridization using incompatible specific rep probes. Plasmids of 9 strains hybridized with repP probe, plasmids of 5 strains hybridized with repW probe and one plasmid hybridized with repQ probe. Fingerprint and cluster analyses of plasmids from 10 strains of B. solanacearum digested with Eco RI revealed that plasmids of race 3 strains clustered in one group and the plasmids of race 1 strains clustered in another group.
