Elevation of Pectobacterium carotovorum subsp. odoriferum to species level as Pectobacterium odoriferum sp. nov., proposal of Pectobacterium brasiliense sp. nov. and Pectobacterium actinidiae sp. nov., emended description of Pectobacterium carotovorum and description of Pectobacterium versatile sp. nov., isolated from streams and symptoms on diverse plants
Résumé
The species corresponds to a complex, including two subspecies with validly published names, two proposed subspecies and two new species, and Recent studies suggested that this complex needed revision. We examined the taxonomic status of 144 strains isolated from a wide range of plant species, various geographical origins and waterways. Sequences of the , and housekeeping genes clustered 114 of these strains together within a not yet described clade. We sequenced eight strains of this clade and analysed them together with the 102 genomes available in the NCBI database. Phylogenetic analysis, average nucleotide identity calculation and DNA-DNA hybridization allowed us to differentiate seven clades. This led us to propose the elevation of subsp. to species level as sp. nov. (type strain CFBP 1878=LMG 5863=NCPPB 3839=ICMP 11533), the proposal of sp. nov. (type strain KKH3=LMG 26003 =KCTC 23131) and sp. nov. (type strain CFBP 6617= LMG 21371=NCPPB 4609), to emend the description of (type strain CFBP 2046=LMG 2404=NCPPB 312=ICMP 5702), and to propose a novel species, sp. nov (type strain CFBP6051= NCPPB 3387=ICMP 9168) which includes the strains previously described as 'Candidatus '. Phenotypic analysis performed using Biolog GENIII plates on eight strains of sp. nov. and related strains completed our analysis.
