Evolutionary History of Lepidopteran Genes Associated with Sex Pheromone Recognition
- 30 Downloads
Insect genes encoding odorant receptors (ORs) and odorant-binding proteins (OBPs) comprise Lepidoptera (moths and butterflies)-specific subfamilies named pheromone receptors (PRs) and pheromone-binding proteins (PBPs), respectively. Both subfamilies are monophyletic, and some of the genes in these groups are responsible for sex pheromone recognition. Recent progress in sequencing by next-generation sequencers has facilitated the detection of gains, losses, and translocations of these genes, which have occurred in a wide variety of lepidopteran lineages. The evolutionary history of these genes provides valuable insights into how the sex pheromone recognition system has evolved in Lepidoptera.
