    Abstract

    These studies identified new resistances in Brassicaceae against white leaf spot disease (Pseudocercosporella capsel/ae), defined resistance mechanisms such as inhibition of conidial germinat ion, demonstrated formation of unique structures containing cercosporin in and on infected tissues , confirmed the mycotoxin cercosporin as an important 'pathogenicity factor ' for host invasion, and highlighted both the uniqueness of Western Australian pathogen isolates and especially those from wild weedy species. These studies have provided critical new knowledge on this pathogen and the disease it causes, enabling for the first time the development of novel, more effective control measures based on host resistance.
