A comparative genomic study (in 2020) analyzed 494 complete genomes from the entire "Pseudomonas" genus, with 25 of them being annotated as "P. fluorescens". The phylogenomic analysis clearly showed that the 25 strains annotated as "P. fluorescens" did not form a monophyletic group. In addition, their Average Nucleotide Identities did not fulfil the criteria of a species, since they were very diverse. It was concluded that "P. fluorescens" is not a species in the strict sense, but should be considered as a wider evolutionary group, or a species complex, that includes within it other species too. This finding is in accordance with previous analyses of 107 "Pseudomonas" species, using four core 'housekeeping' genes, that consider "P. fluorescens" as a relaxed species complex.
