Phylogenetic placement of the symbiotic bacteria from the acanthosomatid stinkbugs in the γ-Proteobacteria on the basis of 16S rRNA gene sequences. A total of 1271 aligned nucleotide sites were subjected to the analysis. A Bayesian phylogeny is shown. On the nodes, posterior probabilities in the Bayesian analysis are shown above, and bootstrap probabilities (maximum parsimony (MP) analysis/maximum likelihood (ML) analysis) are shown below. Branches supported by less than 50% posterior probabilities were collapsed into polytomies. Asterisks indicate support values lower than 50%. Sequence accession numbers are in brackets. Percent AT contents of the sequences are in parentheses.
