Natural variation in black rot resistance
in Brassica

The Brassica genus is well-known for its agricultural important species, including many cabbage vegetables and oilseed crops. One of the most destructive diseases of Brassica crops worldwide is black rot, caused by the bacterium Xanthomonas campestris campestris. The current genetic base of black rot resistance in cabbage is narrow, and as such most cultivars are not providing adequate resistance. Screening of biodiverse Brassica panels allows to broaden this genetic base and to introduce robust black rot resistance in cabbage. Via comparative genomic studies and association mapping we try to identify the underlying black rot resistance genes.
