Fig. 8From: Differential gene expression in the evolution of sex pheromone communication in New Zealand’s endemic leafroller moths of the genera Ctenopseustis and PlanotortrixMaximum likelihood tree showing the evolutionary relationships among odorant binding proteins (OBPs). The tree includes the genes isolated from the New Zealand leafroller moths Ctenopseustis herana (Cher, highlighted in blue), C. obliquana (Cobl, highlighted in light purple), Planotortrix excessana (Pexc, highlighted in light green) and P. octo (Poct, highlighted in dark green) and the horticultural pest Epiphyas postvittana (Epos, highlighted in orange). Circles at the nodes represent the Shimodaira-Hasegawa local support, with colours and size of circles being proportional to the percentage of support (0–100%). Groups shades in green were antennae biased in male compared to females, whereas orange shaded groups were pheromone gland biased. Groups in blue indicate genes under positive selection.
