Figure 3. 16S rRNA phylogeny of Sodalis in Hippoboscidae inferred by BI analysis.

Posterior probabilities and bootstrap support are printed upon branches, respectively (asterisk was used for very low or missing bootstrap branch support). Taxa labelled with voucher are newly sequenced in this study. Taxa in dark purple represent Sodalis-like bacteria which genome was sequenced. Numbers behind these taxa correspond to their GC content of 16S rRNA, GC content of genome, and genome size, respectively. Numbers behind other taxa correspond to GC content of their 16S rRNA. Red lineages correspond to obligate symbionts while orange lineage is symbiont of recent origin. The red dashed line shows that co-evolution between Icosta spp. and their obligate endosymbiont imperfect.
