Black rot (Xanthomonas campestris pv. campestris, Xcc) is one of the most devastating disease of Brassica crops worldwide. Breeding varieties with black rot resistance genes is the most economical and environmentally friendly way to control black rot. However, Brassica germplasm resources for black rot resistance are very scarce, and no black rot resistance genes have been cloned to date, and the mechanism of black rot resistance is still unclear. My ongoing research include 1) cloning and verifying the function of black rot resistance gene, 2) analyzing its molecular mechanism, 3) developing Brassica oilseed rape, cabbage and Chinese cabbage germplasms or varieties with broad-spectrum resistance to multiple black rot races. Our major goal is to provide Brassica crop breeding with breakthrough resource for the broad-spectrum resistance, but also broaden theoretical knowledge of the crop broad-spectrum resistance.
