Necrotrophic Effector Epistasis in the Pyrenophora tritici-repentis-Wheat Interaction
Pyrenophora tritici-repentis, the causal agent of tan spot disease of wheat, mediates disease by the production of host-selective toxins (HST). The known toxins are recognized in an 'inverse' gene-for-gene manner, where each is perceived by the product of a unique locus in the host and recognition leads to disease susceptibility. Given the importance of HSTs in disease development, we would pre...
متن کاملCharacterization of Pyrenophora tritici-repentis (Tan Spot of Wheat) Races in Baltic States and Romania
Tan spot, caused by the fungus Pyrenophora triticirepentis, is economically important foliar disease in Latvia, Lithuania, and Romania; however, race structure from Baltic States and Romania is not known. In this study, we performed genotypic and phenotypic race characterization of a large collection of P. triticirepentis isolates from these countries to determine race structure and utilize thi...
متن کاملChromosome-based molecular characterization of pathogenic and non-pathogenic wheat isolates of Pyrenophora tritici-repentis.
The ToxA gene of Pyrenophora tritici-repentis encodes a host-selective toxin (Ptr ToxA) that has been shown to confer pathogenicity when used to transform a non-pathogenic wheat isolate. Major karyotype polymorphisms between pathogenic and non-pathogenic strains, and to a lesser extent among pathogenic strains, and among non-pathogenic strains were identified. ToxA was localized to a 3.0 Mb chr...
متن کاملSimple Method to Produce in vitro Pyrenophora tritici-repentis Teleomorph
A fungus Pyrenophora tritici-repentis induces tan spot of wheat which is a foliar disease that causes yield loss to wheat crops worldwide. In this study, a new, simple and non-costly technique was performed to produce the sexual stage of this fungus in culture, within 9 weeks using wheat straw. This protocol will be helpful to researchers studying the biology of sexual stage development, diseas...
متن کاملGeneration of a ToxA knockout strain of the wheat tan spot pathogen Pyrenophora tritici-repentis.
The necrotrophic fungal pathogen Pyrenophora tritici-repentis causes tan spot, a major disease of wheat, throughout the world. The proteinaceous effector ToxA is responsible for foliar necrosis on ToxA-sensitive wheat genotypes. The single copy ToxA gene was deleted from a wild-type race 1 P. tritici-repentis isolate via homologous recombination of a knockout construct. Expression of the ToxA t...
