Host‐selective toxins, Ptr ToxA and Ptr ToxB, as necrotrophic effectors in the Pyrenophora tritici‐repentis–wheat interaction

摘要: Host-selective toxins (HSTs) are effectors produced by some necrotrophic pathogenic fungi that typically confer the ability to cause disease. Often, diseases caused pathogens produce HSTs follow an inverse gene-for-gene model where toxin production is required for disease and a single locus in host responsible sensitivity susceptibility. Pyrenophora tritici-repentis represents ideal pathogen studying biological significance of such interactions, because it displays complex race structure based on its multiple HSTs. Ptr ToxA ToxB two proteinaceous P. structurally unrelated appear evoke different responses, yet each confers This review will summarize current knowledge how these dissimilar display distinct modes action, pathogenicity tritici-repentis.
