Phylogenetic relationship between
symbionts of heteropteran bugs and other insects inferred from 16S rRNA gene sequences (1204 aligned nucleotide sites). A Bayesian phylogeny is shown with statistical support values (50% or higher) at the nodes: posterior probabilities of Bayesian analysis/bootstrap probabilities of maximum likelihood analysis. Asterisks indicate support values lower than 50%. Sequences obtained from stinkbugs are highlighted by boldface, wherein collection localities are indicated in parentheses and accession numbers in brackets.
