Figure 4

Maximum likelihood tree of the gustatory receptor proteins (GRs) predicted from the antennal transcriptome of R. palmarum and from several species. Unrooted. Includes sequences from C. formicarius (Cfor), D. ponderosae (Dpon) and R. ferrugineus (Rfer). The best substitution model calculated and used corresponded to JTT + G + F. Numbers at nodes represent bootstrap support (n = 100) and are only shown if ≥ 75. GR subfamilies are named and colour coded as follows: purple for candidate CO2 tuned receptors, pink for putative fructose receptors, green for putative conserved general sugar receptors, and dark green for putative bitter receptors. Sequence names of R. ferrugineus and R. palmarum have been colored in red and blue font, respectively.
