FIGURE 1.

Position of the Brucellaceae genomes in the Rhizobiales phylogeny. The ML phylogenetic tree was computed using RaxML from an alignment of 145 core proteins, and rooted using two Caulobacteriales genomes (depicted in gray). Branching support was estimated using 100 bootstrap replicates, with only values lower than 100% displayed. The Brucellaceae clade is indicated with gray background. Brucellaceae type strains are highlighted with bold labeling. A star indicates a genome sequenced in the current study. Pseudochrobactrum, Falsochrobactrum, and Ochrobactrum clade 1 and clade 2 are indicated with pink, purple, orange, and blue backgrounds, respectively. The misclassified Mycoplana dimorpha genome is labeled in red. Branching of Falsochrobactrum spp. is depicted in dashed lines to reflect conflicting topology with the phylogeny displayed in Figure 2.
