They impede the spread of biotrophic pathogens via stimulating cell death and hypersensitive response (HR), and, on the other hand, they provide access to nutrients for necrotrophic pathogens feeding on dead tissues and facilitate their colonizing the host. The participation of ROS in defending plants from pathogens with a combined lifestyle (hemibiotrophs) is not yet understood, and it varies in its dependence on the particular host–pathogen combination. In the present study, we inoculated rapeseed plants (Brassica napus) with a hemibiotrophic fungus, Leptosphaeria maculans, and manipulated the H2O2 content in cotyledons by infiltrating catalase and/or H2O2 into tissues. The action of catalase resulted in a significant decrease in lesions development, but when H2O2 was applied instead, lesion formation was only moderately stimulated compared to the untreated control.
