From: Phylogenomics and signature proteins for the alpha Proteobacteria and its main groups
Character compatibility cliques showing the two largest cliques of mutually compatible characters based on the two states sites in the concatenated sequence alignment for 12 conserved proteins. The cliques consisted of 350 mutually compatible characters. The numbers of characters that distinguished different clades are indicated on the nodes. Rooting was done using the sequences for Helicobacter pylori and Campylobacter jejuni. *, as in Figure 1.
