ABSTRACT The fungus Pyrenophora tritici-repentis produces a toxin (Ptr ToxA) that causes rapid cell necrosis in sensitive wheat genotypes. A single recessive gene (tsn1) on chromosome 5BL in common wheat confers insensitivity to this toxin. Our objectives were to analyze the allelic relationships of genotypes that have shown insensitivity to a P. tritici-repentis necrosis-inducing toxin, map the gene for insensitivity to the necrosis-inducing factor produced by P. tritici-repentis in a durum… CONTINUE READING
