Abstract:	The role of active oxygen species has been studied in spreading soft-rot lesions caused by the necrotrophic fungal pathogen B. cinerea in leaves of four genotypes of French bean (P. vulgaris) namely N90598, 416664, Huron and 164214. Large increases were observed for the aldehydic end-products of oxidative damage, malondialdehyde and 4-hydroxy-2-nonenal, as a result of infection in each of the genotypes studied. Similar increases were found in a stable free radical and g=4.27 Fe(III) signals, but not Mn(II) signals, in electron paramagnetic resonance spectra. These changes were accompanied by large decreases in ascorbic acid levels, with changes in the antioxidant glutathione being genotype dependent.
