Abstract excerpt
Leptosphaeria maculans is the ascomycete responsible for one of the most damaging diseases of oilseed rape (Brassica napus), stem canker of crucifers. Both avirulence (AvrLm) genes in the fungus and resistance (Rlm) genes in the plant are genetically clustered. Using a map-based cloning strategy, we delineated a 238 kb region containing the AvrLm7 locus. Structural features of the region were reminiscent of those...
