Brassica oleracea: The Dog of the Plant World.

The horticultural crop Brassica oleracea L. plays an important role in global food systems. Brassica oleracea is unique in that it has been domesticated into several morphotypes (cultivars), including broccoli, Brussels sprout, cabbage, cauliflower, kale, kohlrabi, and several lesser well known morphotypes, such as walking stick kale and marrow cabbage. These crops are widely used as leaf and root vegetables, as well as for animal feed. There are several hypotheses on the origin of these crops. However, cultivation likely originated in the Mediterranean region with additional domestications occurring around the world. One uniting characteristic of these vegetable crops is the presence of glucosinolates, bitter tasting compounds that are useful for their herbivory defense, and potentially have anti-carcinogenic properties. Using this system of diversity within Brassica oleracea, we aim to examine patterns of relationships among morphotypes and wild relatives, including signals of hybridization and introgression. We also plan to elucidate the wild progenitor of B. oleracea to determine its origin of domestication. Lastly, using association mapping techniques, we hope to possibly identify genes underlying quantitative phenotypic traits of economic importance.
