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 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 کاملQuantitative trait loci for resistance to Pyrenophora tritici-repentis race 1 in a Chinese wheat.
Tan spot, caused by Pyrenophora tritici-repentis, is an economically important foliar disease of wheat worldwide. Eight races of the pathogen have been characterized on the basis of their ability to cause necrosis or chlorosis in a set of differential wheat lines. Race 1 produces two host-selective toxins, Ptr ToxA and Ptr ToxC, that induce necrosis and chlorosis, respectively, on leaves of sen...
متن کاملLocalization of Ptr ToxA Produced by Pyrenophora tritici-repentis Reveals Protein Import into Wheat Mesophyll Cells.
The plant pathogenic fungus Pyrenophora tritici-repentis secretes host-selective toxins (HSTs) that function as pathogenicity factors. Unlike most HSTs that are products of enzymatic pathways, at least two toxins produced by P. tritici-repentis are proteins and, thus, products of single genes. Sensitivity to these toxins in the host is conferred by a single gene for each toxin. To study the sit...
