Examination of the role host-selective toxins play in fungal-plant interactions

Creator:

Andrie, Rachael M.

Abstract:

Pyrenophora tritici-repentis, causal agent of tan spot of wheat, produces multiple host-selective toxins (HSTs), including Ptr ToxA, encoded for by ToxA, Ptr ToxB, encoded for by ToxB, and Ptr ToxC. Variable distribution of these three HSTs among different isolates of P. tritici-repentis, both singularly and in all possible combinations, defines...

Pyrenophora tritici-repentis : investigation of factors that contribute to pathogenicity

Creator:

Holman, Thomas W.

Abstract:

Pyrenophora tritici-repentis (Ptr) is the necrotrophic fungus responsible for tan spot of wheat (Triticum aestivum). Ptr causes disease on susceptible wheat cultivars through the production and secretion of host-selective toxins (HSTs). HSTs are compounds that are only known to be produced by fungi and considered to be primary determinants of...

Crystallographic studies of Pyrenophora tritici-repentis ToxA

Creator:

Sarma, Ganapathy N.

Abstract:

Tan spot of wheat is an economically significant disease caused by the fungal pathogen, Pyrenophora tritici-repentis. Certain races of the fungus secrete Ptr ToxA (ToxA), a 13.2 kDa proteinaceous host-selective toxin that is responsible and sufficient to cause disease in susceptible wheat varieties. Disease symptoms develop only when the ToxA...
