WebThis type of parasitism can result in severe economic losses in crops, primarily from the two major biotrophic plant pathogens of rust fungi (Basidiomycota) and powdery mildew (Ascomycota). Necrotrophic fungi infect living plants with the aim of killing the plant at or shortly after infection and extracting nutrients from its dead or dying ... WebReactive oxygen species (ROS) play a major role in pathogen-plant interactions: recognition of a pathogen by the plant rapidly triggers the oxidative burst, which is necessary for further defense reactions. The specific role of ROS in pathogen defense is still unclear.
