Pseudomonas edsoni sp. nov. and Pseudomonas acericola sp. nov.

Pseudomonas acericola sp. nov. is a member of the Pseudomonas fluorescens subgroup, isolated from maple sap (Acer saccharum) in Quebec, Canada. The genome size is approximately 6.18 Mbp with a GC content of 61.37%. Phylogenomic analysis places this species in a distinct clade, with ANI values below 95% and dDDH values below 70% compared to all known type strains.  Diagnostic genomic traits include: Presence of multiple nonribosomal peptide synthetase (NRPS) clusters for cyclic lipopeptides, Presence of quorum-sensing related homoserine lactone (HSL) clusters, with partial similarity to known polyketide and cepacin A clusters; Presence of a terpene and a microcin biosynthetic gene cluster; Absence of phenazine biosynthetic operons, distinguishing it from P. edsoni.

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.
