Pseudomonas edsoni sp. nov. belongs to the Pseudomonas fluorescens subgroup and was isolated from maple sap (Acer saccharum) in Quebec, Canada. The genome size ranges from 6.5–6.6 Mbp with a GC content of ~60.6%. The species is phylogenetically distinct, forming a separate clade supported by ANI values >95% among its members and <95% to other species, and dDDH <70% with all known type strains. Diagnostic genomic traits include:
Presence of a conserved phenazine biosynthetic operon (phzABCDEFG); Multiple nonribosomal peptide synthetase (NRPS) clusters for cyclic lipopeptides; Genes for hydrogen cyanide (hcnABC) production, often in hybrid clusters with NRPS and metallophore genes; Type VI secretion system (T6SS) gene clusters.
