Figure 2. Flux of protein families in Bartonella and related outgroup species.

The flux of protein families has been mapped onto the two most probable phylogenies, “BAnh1 early” shown in Figure 1B) (A) and “Radiation” shown in Figure 1C (B). Genesis (blue) and loss (red) of protein families are depicted above each branch, respectively. Total number of gene families is indicated below the branch. The node number is shown in italics. Abbreviations of Bartonella species are as in Table 1. Abbreviations of outgroup species: AT, Agrobacterium tumefaciens; SM, Sinorhizobium meliloti; ML, Mesorhizobium loti; BMel, Brucella melitensis; OA, Ochrobactrum anthropi; BJap, Bradyrhizobium japonicum.
