  abstract = {{X}anthomonas arboricola comprises a number of economically important fruit tree pathogens classified within different pathovars. {D}ozens of nonpathogenic and taxonomically unvalidated strains are also designated as {X}. arboricola, leading to a complicated taxonomic status in the species. {I}n this study, we have evaluated the whole-genome resources of all available {X}anthomonas spp. strains designated as {X}. arboricola in the public databases to refine the members of the species based on {DNA} similarity indexes and core genome-based phylogeny. {O}ur results show that, of the nine validly described pathovars within {X}. arboricola, pathotype strains of seven pathovars are taxonomically genuine, belonging to the core clade of the species regardless of their pathogenicity on the host of isolation (thus the validity of pathovar status). {H}owever, strains of {X}. arboricola pv. guizotiae and {X}. arboricola pv. populi do not belong to {X}. arboricola because of the low {DNA} similarities between the type strain of the species and the pathotype strains of these two pathovars. {T}hus, we propose to elevate the two pathovars to the rank of a species as {X}. guizotiae sp. nov. with the type strain {CFBP} 7408({T}) and {X}. populina sp. nov. with the type strain {CFBP} 3123({T}). {I}n addition, other mislabeled strains of {X}. arboricola were scattered within {X}anthomonas spp. that belong to previously described species or represent novel species that await formal description.},
