Understanding the development, evolution, and function of bullseye pigmentation patterns in Hibiscus trionum
… patterns are created by spatial differences in pigmentation, cell shape and texture of the adaxial petal epidermis. The mechanisms controlling formation and evolution of these patterns, and their exact role in plant-animal communication are not well understood. My PhD adds to current …

Evolution and Genetics of Floral Color Polymorphisms in Clarkia gracilis ssp. sonomensis and Erythronium umbilicatum
… two polymorphisms involving loss of anthocyanin pigmentation in some of the individuals in the populations. In Chapter 1, I characterized the genetic basis of the “white cup” phenotype in Clarkia gracilis ssp. sonomensis, where no anthocyanins are produced in the basal region of the …

Genetic studies of phenotypic variants in the woodland strawberry, (Fragaria vesca)
… include alterations to floral development, anthocyanin pigmentation and leaf structure. The floral development mutant named green petal (gp) was not associated with the T-DNA insertions present. Based on similar phenotypes induced by mutation of transcription factors involved in floral …

Population structure and the molecular genetics of petal spot pigmentation in Gorteria diffusa
… and to characterise the genes regulating anthocyanin pigmentation within petal spots. For the latter, two additional morphotypes were studied to improve the robustness of conclusions based on comparisons between spotted and plain petal tissues. The anthocyanin cyanidin 3-glucoside was …
