Diversity of Pseudomonas species associated with soft rot of plants in Poland
Journal of Plant Protection Research 41 (1), 67-76
Abstract: A total of 94 pectolytic and 60 nonpectolytic Pseudomonas isolates were obtained from 250 samples of rotted vegetable specimens representing various economically important vegetables. The isolates were identified on the basis of standard biochemical tests. Pseudomonas fluorescens biovar V and II and Pseudomona putida were the most abundant species among pectolytic isolates and Pseudomonas fluorescens biovar I among non-pectolytic ones. Only 3 Pseudomonas viridiflava isolates were identified and all of them were obtained from potato. Isolates of pectolytic phenotype were scattered among nonpectolytic ones irrespective of their taxonomical status. Isolates identified biochemically, as Pseudomonas marginalis were also present in the nonpectolytic group. PCR method is unsuitable for identification and differentiation of bacteria belonging to the pectolytic fluorescent Pseudomonas group due to great diversity of species. However, the results of PCR amplification of the genes encoding pectate lyase suggest that genes responsible for production of this enzyme may also be present in isolates of nonpectolytic phenotype.
