Comparative Genomics of Pseudomonas stutzeri Complex: Taxonomic Assignments and Genetic Diversity.

ABSTRACT: Pseudomonas stutzeri is a species complex with extremely broad phenotypic and genotypic diversity. However, very little is known about its diversity, taxonomy and phylogeny at the genomic scale. To address these issues, we systematically and comprehensively defined the taxonomy and nomenclature for this species complex and explored its genetic diversity using hundreds of sequenced genomes. By combining average nucleotide identity (ANI) evaluation and phylogenetic inference approaches, we identified 123 P. stutzeri complex genomes covering at least six well-defined species among all sequenced Pseudomonas genomes; of these, 25 genomes represented novel members of this species complex. ANI values of ≥∼95% and digital DNA-DNA hybridization (dDDH) values of ≥∼60% in combina
