Phylogenomic analysis of the genus Pseudomonas and reclassification of P. humi, P. zeshuii, P. psychrotolerans, P. nitritireducens, P. pharmacofabricae and P. panacis are later heterotypic synonym of P. citronellolis Lang 2007, P. luteola, P. oryzihabitans, P. nitroreducens Lang 2007, P. fluvialis and P. marginalis (Brown 1918) Stevens 1925 (Approved Lists 1980), respectively

The present study described the comparative genomic analysis of the validly named species of the genus Pseudomonas to define the taxonomic assignment. Genomic information for 208 type strains was available in the NCBI genome database at the time of conducting this analysis. The ANI, AAI and in silico DNA DNA hybridization (isDDH) data were higher than the threshold values for the twelve strains with their closely related type species. Whole genome comparisons shared 97 - 99 % average nucleotide identity, 97.85 to 99.19 % average amino acid identity and 72.80 to 90.40 % digital DNA DNA hybridization values. Further, the phylogenomic analysis based on the core genome confirmed that P. humi CCA1 and P. citronellolis LMG 18378, P. zeshuii KACC 15471 and P. luteola NBRC 103146, P. oryzihabitans DSM 6835 and P. psychrotolerans DSM 15758, P. nitroreducens DSM 14399 and P. nitritireducens WZBFD3-5A2, P. fluvialis CCM 8778 and P. pharmacofabricae ZYSR67-Z, P. panacis DSM 18529 and P. marginalis DSM 13124 formed a monophyletic clade. Thus, we proposed six type species viz., P. humi CCA1, P. zeshuii KACC 15471, P. psychrotolerans DSM 15758, P. nitritireducens WZBFD3 5A2, P. pharmacofabricae ZYSR67 Z and P. panacis DSM 18529 are the later heterotypic synonym of P. citronellolis Lang 2007, P. luteola, P. oryzihabitans, P. nitroreducens Lang 2007, P. fluvialis and P. marginalis (Brown 1918) Stevens 1925 (Approved Lists 1980), respectively considering the priority date of publication. ### Competing Interest Statement The authors have declared no competing interest.
