Remarks: |
A combined phylogenetic and multilocus DNA sequence analysis of 26 Pseudomonas stutzeri strains distributed within the 9 genomovars of the species has been performed. Type strains of the two most closely related species (P. balearica, former genomovar 6, and P. mendocina), together with P. aeruginosa, as the type species of the genus, have been included in the study. The extremely high genetic diversity and the clonal structure of the species were confirmed by the sequence analysis. Clustering of strains in the consensus phylogeny inferred from the analysis of seven nucleotide sequences (16S ribosomal DNA, internally transcribed spacer region 1, gyrB, rpoD, nosZ, catA, and nahH) confirmed the monophyletic origin of the genomovars within the Pseudomonas branch and is in good agreement with earlier DNA-DNA similarity analysis, indicating that the selected genes are representative of the whole genome in members of the species. |

Remarks: |
The potential for natural genetic transformation among the seven genomovars (gvs) of Pseudomonas stutzeri was investigated. Of the 12 strains originating from a variety of environments, six strains (50%) from five gvs were competent for DNA uptake (Rif(R) marker). The transformation frequencies varied over more than three orders of magnitude. With three highly transformable strains (ATCC 17587, ATCC 17641, JM300) from two gvs and all other strains as DNA donors, sexual isolation from other pseudomonad species (Pseudomonas alcaligenes, Pseudomonas mendocina) and also from other P. stutzeri gvs was observed (i.e. heterogamic transformation was reduced). For ATCC 17587 (gv 2) and ATCC 17641 (gv 8), heterogamic transformation was up to two and three orders of magnitude lower with other P. stutzeri gv and the other species employed, respectively, than in homogamic transformations. Interestingly, whereas with ATCC 17587 and ATCC 17641 heterogamic transformation with donors of the same gv was as high as homogamic transformation, JM300 (gv 8) was sexually isolated from its nearest relative (ATCC 17641). Also, sexual isolation of JM300 from other P. stutzeri gvs was most pronounced among the recipients tested, in some cases reaching the highest levels found with the other species as DNA donors (reduction of heterogamic transformation by 4000-fold). Results obtained here from nucleotide sequence analysis of part (422 nt) of the gene for the RNA polymerase ss subunit (rpoB) from various strains indicated that sexual isolation of ATCC 17641 increased with nucleotide sequence divergence. Implications of the observed great heterogeneity in transformability, competence levels and sexual isolation among strains are discussed with regard to the evolution of P. stutzeri. |

Remarks: |
A study of representatives of the bacterial genus Pseudomonas, analysing a combined data set of four molecular sequences with completely different properties and evolutionary constraints, is reported. The best evolutionary model was obtained with a hierarchical hypothesis testing program to describe each data set and the combined data set is presented and analysed under the likelihood criterion. The resolution among Pseudomonas taxa based on the combined data set analysis of the different lineages increased due to a synergistic effect of the individual data sets. The unresolved fluorescens lineage, as well as other weakly supported lineages in the single data set trees, should be revised in detail at the biochemical and molecular level. The taxonomic status of biovars of P. putida is discussed. |
