WebBiotrophic fungi are often obligate pathogens growing within living plant cells, and typically have narrow host ranges. Necrotrophs often use toxins, cell-wall-degrading enzymes, and ROS to promote disease and macerate plant tissues. Some pathogens exhibit both types of nutrition, switching from biotrophic to necrotrophic growth. 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).
