The genus Dickeya is an important group of plant pathogens that currently comprises 10 recognized species. Although most Dickeya isolates originated from infected cultivated plants, they are also isolated from water. The genomic sequence of the Australian strain NCPPB 569 T clearly established its separation from the previously characterized Dickeya species. The average nucleotide identity and digital DNA–DNA hybridization values obtained by comparing strain NCPPB 569 T with strains of characterized Dickeya species were lower than 87 and 32 %, respectively, supporting the delineation of a new species. The name Dickeya poaceiphila sp. nov. is proposed for this taxon with the type strain NCPPB 569 T (=CFBP 8731 T ). Two other strains isolated in Australia, CFBP 1537 and CFBP 2040, also belong to this species. Phenotypic and genomic comparisons enabled the identification of traits distinguishing D. poaceiphila isolates from strains of other Dickeya species.
