Comparison of the phylogenies of representative species of Columbicola spp. and their symbiotic bacteria. Columbicola trees are from maximum likelihood analysis of sequences of the mitochondrial cytochrome oxidase I gene, mitochondrial 12S rRNA gene, and nuclear elongation factor 1alpha gene [21]. Symbiont trees are from Figure 1 (left) and Figure 2 (right) in the current paper. Connecting lines illustrate host-symbiont associations. Bulleted nodes are co-speciation events inferred from reconciliation analysis [22].
