How Chinese cabbage and white cabbage became alike

White cabbage and Chinese cabbage have a lot in common: both have leaves that wrap tightly around each other to form a leafy head. Remarkably, however, these two crops originate from two different Brassica species used and domesticated by farmers on two different continents. In their publication in Nature Genetics, scientists from Wageningen UR show how these two different Brassica species developed (were domesticated) in Europe and Asia, sometimes resulting in very similar crops.
