Arts & Sciences Electronic Theses and Dissertations
The mustard family, Brassicaceae, is a large and economically important group of plants comprising ~350 genera and ~4060 species. Within the family, one genus, Camelina, has been neglected and nearly forgotten until recent decades. This genus comprises between 7 – 9 species, and includes Camelina sativa, an ancient oilseed crop cultivated for thousands of years in Europe. An allohexaploid, C. sativa contains high levels of omega-3 fatty acids and a seed oil composition amenable for production of aviation jet fuel. With a short generation time and ability to be cultivated on marginal soils with few inputs, C. sativa is set …

The Genetic Basis Of Adaptation To Environmental Stress In Two Grass Genomic Model Systems, David Mitchell Goad
Arts & Sciences Electronic Theses and Dissertations
Plants are exposed to a wide variety of environmental stress in the wild and have developed an equally diverse set of adaptations to tolerate them. The evolutionary processes that have led to this functional diversification, and the specific genes and physiological mechanisms involved, are of immense interest to both evolutionary biologists and crop breeders. In this dissertation I investigate adaptation to different types of environmental stress in two economically important grass species, seashore paspalum (Paspalum vaginatum Sw.) and rice (Oryza sativa L.).
Seashore paspalum is a halophytic turfgrass that occupies habitats which can dramatically differ in salt concentration. Populations may …
