Genomic, phylogenetic and catabolic re-assessment of the Pseudomonas putida clade supports the delineation of Pseudomonas alloputida sp. nov., Pseudomonas inefficax sp. nov., Pseudomonas persica sp. nov., and Pseudomonas shirazica sp. nov

Résumé

Bacteria of the Pseudomonas putida group are studied for a large panel of properties ranging from plant growth promotion and bioremediation to pathogenicity. To date, most of the classification of individual pseudomonads from this group relies on 16S RNA gene analysis, which is insufficient for accurate taxonomic characterization within bacterial species complexes of the Pseudomonas putida group. Here, a collection of 20 of these bacteria, isolated from various soils, was assessed via multi-locus sequence analysis of rpoD, gyrB and rrs genes. The 20 strains clustered in 7 different clades of the P. putida group. One strain per cluster was sequenced and results were compared to complete genome sequences of type strains of the P. putida group. Phylogenetic analyses, average nucleotide identity data and digital DNA hybridizations, combined to phenotypic characteristics, resulted in the proposition and description of four new species i.e. Pseudomonas alloputida Kh7 T (= LMG 29756 T = CFBP 8484 T) sp. nov., Pseudomonas inefficax JV551A3 T (= DSM108619 T = CFBP 8493 T) sp. nov., Pseudomonas persica RUB6 T (= LMG 29757 T = CFBP 8486 T) sp. nov. and Pseudomonas shirazica VM14 T (= LMG 29953 T = CFBP 8487 T) sp. nov.
