Fig. 2.

Aligned putative OR protein sequences of Manduca (red), Bombyx (blue), and Heliothis (green). The identified receptor candidates of Manduca are spread evenly inside the family. Two candidates belonging to the subgroup of male pheromone receptors (orange) have been identified. Additionally, female-specific ORs of Bombyx have been marked (blue). Two female-specific receptor groups also include receptor candidates of Manduca. Additional instances with clear homologs in all three species have been indicated by name. Coreceptors (MsexOR-2, BmorOR-2, and HR2) have been excluded.
