Arsenophonus phylogeny constructed using maximum-likelihood (ML) analyses based on the concatenated sequences of three genes: fbaA, ftsK and yaeT. The GTR+I evolution model was used to reconstruct this phylogeny. Bootstrap values are shown at the nodes for ML analysis. For nodes also supported by Bayesian inferences, the corresponding posterior probability is shown after the bootstrap value obtained by ML estimations. The tree was midpoint rooted. Recombinant individuals are indicated with an asterisk.
