Title: In vitro activity of glucosinolates and their products against Leptosphaeria maculans
Abstract: Effects of a variety of glucosinolates and their hydrolysis products on the growth of Leptosphaeria maculans in culture were examined. When hydrolysed with myrosinase, reaction products of all the glucosinolates tested, except progoitrin (2-hydroxy-3-butenyl glucosinolate), were inhibitory; 2-propenyl isothiocyanate, derived from sinigrin, was the most toxic. Antifungal activity of indole hydrolysis products of glucobrassicin (3-indolylmethyl glucosinolate) and 1-methoxy glucobrassicin are described for the first time. Levels of glucosinolates reported to occur in leaves of oilseed rape correspond with levels shown here to be sufficient to generate strongly antifungal hydrolysis products. The significance of these compounds in resistance to L. maculans is discussed. In this context the presence of indole glucosinolate in disproportionately high levels in low glucosinolate cultivars of oilseed rape is of considerable interest.
