Morning Glory Floral Evolution

Morning glory flowers present diversity in color, shape, and size. As with many groups of flower plants, we are interested in understanding this variation in floral form. Working in collaboration with Silvana Martén-Rodríguez and Mauricio Quesada, we are examining the evolution of floral traits and breeding systems among an American group of morning glories, members of Ipomoea subgenus Quamoclit. An important contribution of this research is consideration of the role of adaptation to different pollinators, as we all as the influence of mating system plays in shaping floral phenotypes. These are two important axes that both need to be considered simultaneously. Silvana’s research group is providing the critical pollinator records and estimates of selfing rate and together we are constructing a species-level phylogeny for the Quamoclit clade.
