Characterization of Pyrenophora Tritici-Repentis in Wheat and Rye to Study Tan Spot Susceptibility and Insights Into Its Relationship with Stem Rust Resistance
<p>Tan spot, caused by the ascomycete fungus, Pyrenophora tritici-repentis (Ptr), is a major foliar fungal disease of wheat worldwide. To date, Ptr isolates have been grouped into eight races based on the production of three host selective effectors (toxins), Ptr ToxA, ToxB, and ToxC, which are …

Effects of the Lr34 and Lr46 rust-resistance genes on other diseases of wheat
Lr34 and Lr46 are adult plant resistance genes providing durable resistance to biotrophic diseases of wheat like rusts and powdery mildew. In seedlings, these genes increased susceptibility to Septoria tritici blotch (STB), caused by Zymoseptoria tritici, in near-isogenic lines (NILs) of spring …

Evaluating Fungicide Timing for Leaf Spot Diseases of Wheat and Fungicide Resistance in Pyrenophora tritici-repentis
… most common diseases affecting wheat are leaf spots, caused by several pathogen species that make up the leaf spotting complex, including tan spot of wheat, caused by Pyrenophora tritici-repentis. The optimal timing to apply fungicide to protect wheat against leaf spots is during the flag leaf …
