Abstract excerpt

The ascomycete Pyrenophora tritici-repentis (Ptr) is the causal agent of tan spot, a common and economically important wheat disease worldwide. Three necrotrophic effectors (NEs), known as Ptr ToxA, Ptr ToxB, and Ptr ToxC, have been identified from the fungal pathogen as major virulence factors. The race 2 isolate 86-124 which produces Ptr ToxA is capable of causing disease on wheat lines that is insensitive to...
