Abstract

Nearly complete sequences of 16S rRNA genes were determined for 8 bacterial strains representing 5 species of the rRNA homology group II pseudomonads that are members of the beta subclass of the class Proteobacteria. Comparative analysis with published sequence data indicated that Pseudomonas andropogonis, P. caryophylli, P. gladioli pv. gladioli and P. cepacia aggregate in one coherent cluster at 94.2% sequence similarity; P. solanacearum and P. pickettii shared 95.3% and 92.8% similarity, respectively, with Alcaligenes eutrophus in another cluster. Both clusters joined at 87.8% similarity, which is similar to that for genera in this subclass of Proteobacteria. Based on this study and on comparison with other works it is suggested that these species are separated from authentic pseudomonads and constitute a new genus or possibly 2 related genera accommodating P. andropogonis, P. caryophylli, P. gladioli, P. cepacia and P. solanacearum, P. pickettii and A. eutrophus, respectively. Four strains of P. solanacearum representing Biovars 1, 2, 3 and 4 were subdivided into 2 clusters at 99.1% sequence similarity, in agreement with other published phenotypic and genotypic studies. The 2 clusters may be potentially regarded as subspecies
