Bayesian phylogenetic tree for the RNase HI domains. A phylogenetic tree was constructed by using Bayesian inference on the basis of the alignments of RNase HI domain sequences from 12 species in the gammaproteobacteria, as listed in Additional File 4. Species names followed by Arabic numerals are used to distinguish multiple forms of RNase HI in a genome; names not followed by Arabic numerals indicate the presence of a single RNase HI in a genome. Numbers at the nodes represent posterior probabilities. The scale bar equals 0.1 substitutions per site.
