Distribution of normalized dN-dS in reduviid oxidative phosphorylation complex subunits. Codon-by-codon Maximum Likelihood analysis was calculated for each ortholog using the HyPhy package [42]. The normalized dN-dS for each variant position was plotted according to increasing median value from left to right. Positive values indicate likelihood of selection. a Complex I. Core mitochondrial subunits (light blue), core nuclear-encoded subunits (dark blue), accessory A subunits (purple), accessory B subunits (pink); b Complex III. Respiratory subunits (light blue), core subunit (purple), low molecular weight subunits (pink); c Complex IV. Mitochondria-encoded subunits (purple); and d) ATPase complex. F1 ATPase subunits (yellow), Nuclear-encoded F0-ATPase subunits (orange) and mitochondria-encoded F0 subunits (red). Significant differences (one-way ANOVA test corrected for multiple comparison) in dN-dS distribution are shown under black bar. Red arrows indicate subunits participate in the oligomerization of respiratory supercomplexes in mammals [77]. A full description of coding genes involved in oxidative phosphorylation is described in Additional file 9
