Chinese cabbage (Brassica rapa L. ssp pekinensis) is one of the most important leafy vegetables cultivated worldwide. Clubroot disease caused by a soil-borne obligate biotrophic Plasmodiophora brassicae (Pb) severely affects the yield and quality of cruciferous crops, especially Chinese Cabbage. BraCRa, as one of the earliest cloned clubroot resistance genes, confers race-specific resistance to Pb.
