El desarrollo de variedades trigo (Triticum aestivum L.) debe considerar, además alta capacidad rendimiento, otros caracteres importantes como la resistencia genética a enfermedades. objetivo este trabajo fue evaluar en harinero planta adulta roya lineal (Puccinia striiformis f. sp tritici Wensted.) y hoja recondita Rob. Ex. Desm. sp. tritici), familias F5 provenientes siete ciclos selección re...

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...

Aim of study: Septoria tritici blotch (STB), caused by the fungus Zymoseptoria tritici, is one most important wheat diseases worldwide, affecting both bread and durum wheat. The lack knowledge about interaction with Z. together limited resources resistant material, have led to a rising threat for cultivation, particularly in Mediterranean Basin. In Spain, STB has increased its incidence last fe...

the 1rs chromosome segment derived from petkus rye carries genes for resistance to three wheat rust diseases, namely lr26 for resistance to leaf rust (caused by puccinia triticina), yr9 for resistance to stripe rust (p.striiformis f. sp. tritici) and sr31 for resistance to stem rust (p. graminis f. sp. tritici). since sec-1 is tightly linked with the three rust resis-tance genes electrophoresis...

Inferring reproductive and demographic parameters of populations is crucial to our understanding of species ecology and evolutionary potential but can be challenging, especially in partially clonal organisms. Here, we describe a new and accurate method, cloncase, for estimating both the rate of sexual vs. asexual reproduction and the effective population size, based on the frequency of clonemat...

We recently showed that the wheat pathogen Stagonospora nodorum produces proteinaceous host-selective toxins (HSTs). These toxins include SnTox1 as well as SnToxA, a HST first identified from Pyrenophora tritici-repentis that was implicated in a very recent horizontal gene transfer event from S. nodorum to P. tritici-repentis. Compelling evidence implicating SnToxA and SnTox1 in disease develop...
