Genome-based Geobacteraceae phylogeny. Bayesian inference of the phylogenetic tree of the six Geobacteraceae species discussed in the text, using another Deltaproteobacterial species, Anaeromyxobacter dehalogenans, as the outgroup. The tree was based on a concatenation of the proteins in the 481 families that had exactly one ortholog conserved in each of the seven genomes (see Additional file 6). Values at branch points are posterior probabilities.
