The necrotrophic fungal pathogen Pyrenophora tritici‐repentis (Ptr) causes the major wheat disease tan spot, and produces multiple effectors that contribute to virulence. proteinaceous effector ToxA induces necrosis in genotypes possessing Tsn1 gene, although importance of ToxA– interaction itself varietal development has not been well studied. Here, 40 Australian spring varieties were assessed for sensitivity response a race 1 wildtype Ptr isolate ‐deleted strain at both seedling tillering...
Tan spot disease is caused by Pyrenophora tritici-repentis (Ptr), one of the major necrotrophic fungal pathogens that affects wheat crops globally. Extensive research has shown effectors ToxA, ToxB, and ToxC underlie genetic interactions Ptr race classification. ToxA ToxB are both small proteins secreted during infection; however, structure remains unknown. In line with recent discovery ToxC1 gene involved in production, a subset 68 isolates collected from Australian cropping regions were...
Abstract The virulence of 57 Australian isolates Pyrenophora tritici ‐ repentis (Ptr), a necrotrophic fungal pathogen responsible for the major wheat disease tan spot, was assessed through plant infection assays. Isolates collected from northern, southern, and western wheat‐cropping regions Australia were evaluated against 16 bread cultivars under controlled growth conditions. Following infection, panel displayed varying symptoms ranging tiny necrotic specks to spreading chlorotic lesions....
The necrotrophic effector ToxA is a well-studied virulence factor produced by several fungal necrotrophs. Initially cloned from the wheat tan spot pathogen
