The phylogeny of Sodalis-like symbionts as reconstructed using surface-encoding loci.

ABSTRACT: Phylogenetic analyses of 16S rRNA support close relationships between the Gammaproteobacteria Sodalis glossinidius, a tsetse (Diptera: Glossinidae) symbiont, and bacteria infecting diverse insect orders. To further examine the evolutionary relationships of these Sodalis-like symbionts, phylogenetic trees were constructed for a subset of putative surface-encoding genes (i.e. ompA, spr, slyB, rcsF, ycfM, and ompC). The ompA and ompC loci were used toward examining the intra- and interspecific diversity of Sodalis within tsetse, respectively. Intraspecific analyses of ompA support elevated nonsynonymous (dN) polymorphism with an excess of singletons, indicating diversifying selection, specifically within the tsetse Glossina morsitans. Additionally, interspecific ompC comparisons between Sodal
