| Popis: | Fluorescent oxidase negative pseudomonads (FONP) include Pseudomonas syringae pathovars and related species (P. amygdali, P. avellanae, P. ficuserectae, P. meliae, P. savastanoi and P. viridiflava). Using DNA-DNA hybridization, 9 genomospecies have been delineated among FONP, two of them being elevated to species level, P. tremae and P. cannabina (2). Analyses of 16S rDNA sequences have shown that Pseudomonas sensu stricto included two intrageneric clusters, designated P. aeruginosa and P. fluorescens. Five lineages were defined in P. fluorescens cluster : P. fluorescens, P. syringae, P. cichorii, P. putida and P. agarici lineages (3). Comparisons of 16S rDNA sequences of pseudomonads revealed three hypervariable (hv) regions : hv1 (positions 71–95), hv2 (positions 455–475) and hv3 (positions 998–1043) (3). |
