From: Phylogenomics and signature proteins for the alpha Proteobacteria and its main groups
A neighbour-joining distance tree based on concatenated sequences for 12 conserved proteins. The numbers on the nodes indicate bootstrap scores (out of 100) observed in the neighbour-joining (NJ), maximum parsimony (MP) and maximum-likelihood (ML) analyses (NJ/MP/ML). The species marked with * are presently not part of the Caulobacterales order, but the results of phylogenetic and phylogenomic studies presented here suggest their placement in this group.
