Although most Dickeya isolates originated from infected cultivated plants, they have also been repeatedly isolated from water. To better understand the natural diversity of Dickeya , a survey was performed in small lakes surrounded by wetlands in the French region of La Dombes. Several Dickeya isolates were obtained from water or plants from lakes protected from direct agricultural inputs. Sequencing of the gapA gene revealed that five isolates, S12, S15, S24, S29T and S39, belong to a phylogenetic group separated from other Dickeya species. The genomic sequence of strain S29T clearly established its separation from the other known Dickeya species. The in silico DNA–DNA hybridization (isDDH) and average nucleotide identity (ANI) values (<33 and <88 %, respectively) obtained by comparing strain S29T with strains of characterized Dickeya species supported the delineation of a novel species. The closest species to strain S29T is Dickeya aquatica , previously isolated from rivers, suggesting that these strains have a common ancestor adapted to a water environment. Genomic and phenotypic comparisons enabled the identification of traits distinguishing isolates S12, S15, S24, S29T and S39 from D. aquatica and from other Dickeya species. The name Dickeya lacustris sp. nov. is proposed for this taxon with S29T (=CFBP 8647T=LMG 30899T) as the type strain.", }
