Abstract

Pectobacterium wasabiae was originally isolated from Japanese horseradish (Eutrema wasabi), but recently some Pectobacterium isolates collected from potato plants and tubers displaying blackleg and soft rot symptoms were also assigned to P. wasabiae. Here, combining genomic and phenotypical data, we re-evaluated their taxonomic position. PacBio and Illumina technologies were used to complete the genome sequences of P. wasabiae CFBP 3304T and RNS 08-42-1A. Multi-locus sequence analysis showed that the P. wasabiae strains RNS 08-42-1A, SCC3193, CFIA1002 and WPP163, which were collected from potato plant environment, constituted a separate clade from the original Japanese horseradish P. wasabiae. The taxonomic position of these strains was also supported by calculation of the in-silico DNA-DNA hybridization, genome average nucleotide indentity, alignment fraction and average nucleotide indentity values. In addition, they were phenotypically distinguished from P. wasabiae strains by producing acids from (+)-raffinose, α-d(+)-α-lactose, d(+)-galactose and (+)-melibiose but not from methyl α-d-glycopyranoside, (+)-maltose or malonic acid. The name Pectobacterium parmentieri sp. nov. is proposed for this taxon; the type strain is RNS 08-42-1AT (=CFBP 8475T=LMG 29774T).
