Proteomic tree of 23 class Pseudomonadales species. The probe-set frequency patterns of 23 species belonging to class Pseudomonadales are shown by the clustered color tracks. Most species of this class are free-living microorganisms; however, genus Acinetobacter is an exception. Acinetobacter species are mainly host-associated. The classification tree and the clustered color tracks show that the Acinetobacter species, which are encircled by the dotted line and correspond to the 7 innermost color tracks, form a distinct cluster from other Pseudomonadales species.
