The Evolution And Reproductive Ecology Of Oenothera (Onagraceae)
… and phylogenetic approaches. Oenothera: Onagraceae) is a model system for studying plant reproductive biology. It provides excellent examples of shifts in reproductive traits such as pollination and breeding system, features that have been important in angiosperm diversification. These …

Pollination Limitation to Reproductive Success in the Missouri Evening Primrose, Oenothera Macrocarpa (Onagraceae)
Pollination limitation was investigated in three Missouri populations of Oenothera macrocarpa, a hawkmoth-pollinated, perennial herb. The populations represented extremes in size and habitat quality. Fertilization success (proportion of ovules fertilized) increased following supplementation with …

Evolution of floral and mating system variation in Camissoniopsis cheiranthifolia (Onagraceae): An evaluation of patterns and processes
… variation in Camissoniopsis cheiranthifolia (Onagraceae), a species that exhibits divergence in key floral traits expected to be associated with variation in the relative importance of outcrossing vs. self-fertilization. I combined geographic surveys of floral variation with genetic estimates …

The Role of Visual and Olfactory Cues in Host Recognition for the Specialist Bee Genus Diadasia, and Implications for the Evolution of Host Choice
… of five plant families: Cactaceae, Malvaceae, Onagraceae, Asteraceae, and Convolvulaceae. Assuming a common ancestor for all Diadasia specialized on just one plant, this indicates host-switches in the past, and an ability to recognize more than one flowering plant. I hypothesized that host …

Role of subfunctionalized MYB paralogs in the evolution of pigmentation patterning in Clarkia
… Clarkia species and six outgroup species in the Onagraceae family to explore the origin and role of these duplicated MYBs. Presence of these MYB paralogs in the petal transcriptomes of the outgroup species indicate that they duplicated long before the origin of Clarkia, and while all three seem …
