Bayesian consensus trees of the insect Obp83-like proteins. Phylogenetic trees based on amino acid (A) and nucleotide (B) sequence data. Each sequence is identified as in Figure 2. The numbers indicate the Bayesian probabilities for each phylogenetic clade. Shaded boxes denote the three Drosophila Obp83 orthologs. The scale bars represent amino acid and nucleotide substitutions per site, respectively.
