analysis, similar species have been placed in its group. A comparative genomic and phylogenomic study in 2020, analyzed 494 complete genomes from the entire ''Pseudomonas'' genus, with 43 of them being ''P. chlororaphis'' strains. In this study, the ''P. chlororaphis'' species was determined, based on its monophyly and criterion of Average Nucleotide Identity. This species lies within the wider ''P. fluorescens'' species complex, as determined by. The protein count and GC content of the strains of this species ranged between 5599–6401 (average: 6076) and between 61.9–64% (average: 62.8%), respectively. In addition, the 43 ''P. chlororaphis'' proteomes contained 3587 core proteins (shared among all strains of the species), with 11 core proteins being specific for that group and thus absent in all other strains of the ''Pseudomonas'' genus. Two of these 11 group-specific core proteins are a holin family bacteriocin and a mitomycin-like biosynthetic protein and they may confer a competitive advantage against other root-colonizers.

The ''Pseudomonas chlororaphis'' group

''Pseudomonas chlororaphis'' lends its name to a subgroup within the genus ''

Pseudomonas ''Pseudomonas'' is a genus of Gram-negative, Gammaproteobacteria, belonging to the family Pseudomonadaceae and containing 191 described species. The members of the genus demonstrate a great deal of metabolic diversity and consequently are able t ...

''. The other members of the ''P. chlororaphis'' subgroup are '' P. aurantiaca'', '' P. aureofaciens'', '' P. fragi'', '' P. lundensis'', and '' P. taetrolens''.
