The glucosinolate contents of two different cultivars of Brassica rapa (Herfstraap and Oleifera) infected with Leptosphaeria maculans and Fusarium oxysporum were determined. Infection triggered the accumulation of aliphatic glucosinolates (gluconapin, progoitrin, glucobrassicanapin and gluconapoleiferin) and indole glucosinolate (4-hydroxy-glucobrassicin) in Herfstraap and of two indole glucosinolates (glucobrassicin and 4-hydroxy-glucobrassicin) in Oleifera. While total and aliphatic glucosinolates decreased significantly in Oleifera, a large increase was observed in Herfstraap after fungal infection. The indole glucosinolate glucobrassicin accumulated in Oleifera at a higher rate than Herfstraap especially after infection with F. oxysporum. Apparently the interaction between fungus and B. rapa is cultivar and fungal species specific.
