General Information

General Information Comment Organism
evolution the taxa closely related to Mimulus lewisii have evolved several diff erent pollination syndromes, including hummingbird pollination and self pollination (autogamy), floral scent variation contributing to species diversification in this clade, E-beta-ocimene emission within this Mimulus clade does only occur in Mimulus lewisii, given the very low E-beta-ocimene emission in vivo, Mimulus parishii has a fully functional ocimene synthase enzyme in vitro, the other taxa do not emit E-beta- ocimene from flowers, overview Erythranthe lewisii
physiological function E-beta-ocimene, a monoterpene produced by ocimene synthase (OS) in Mimulus lewisii, is a floral scent important in attracting the species' bumblebee pollinators Erythranthe lewisii
