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...

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...

Characterization of the molecular foundations and biochemistry of alkane and ether oxidation in a filamentous fungus, a Graphium species.

Creator:: Skinner, Kristin M.
Abstract:: Graphium sp., a eukaryotic alkanotroph, is able to oxidize small-molecular weight gaseous n-alkanes, diethyl ether and the branched ether, methyl tert butyl ether (MTBE). However, information regarding the biochemistry of fungal-mediated alkane and ether metabolism is limited, and questions regarding the identity of alkane oxidation catalysts and the genetic underpinnings...

Small secreted proteins of pyrenophora tritici-repentis and their role in wheat Infection

Creator:: Hernandez, Jason, Manning, Viola, Pandelova, Iovanna, and Ciuffetti, Lynda M.
Abstract:: Host-selective toxins (HSTs) secreted by the pathogenic isolate of Pyrenophora tritici-repentis, BFP, are major pathogenicity factors in tan spot disease of wheat. Along with characterized HSTs such as Ptr ToxA (ToxA), BFP secretes at least two more uncharacterized toxic components. In an attempt to identify these additional components, 12 candidate...

Host-Selective Toxins of Pyrenophora tritici-repentis Induce Common Responses Associated with Host Susceptibility

Creator:: Pandelova, Iovanna, Figueroa, Melania, Wilhelm, Larry J., Manning, Viola A., Mankaney, Aakash N., Mockler, Todd C., and Ciuffetti, Lynda M.
Abstract:: Pyrenophora tritici-repentis (Ptr), a necrotrophic fungus and the causal agent of tan spot of wheat, produces one or a combination of host-selective toxins (HSTs) necessary for disease development. The two most studied toxins produced by Ptr, Ptr ToxA (ToxA) and Ptr ToxB (ToxB), are proteins that cause necrotic or chlorotic...

Effects of host resistance on Mycosphaerella graminicola populations

Creator:: Cowger, Christina
Abstract:: Mycosphaerella graminicola (anamorph Septoria tritici) causes Septoria tritici blotch, a globally important disease of winter wheat. Resistance and pathogenicity generally vary quantitatively. The pathogen reproduces both sexually and asexually, and the pathogen population is highly genetically variable. Several unresolved questions about the epidemiology of this pathosystem are addressed by this...

Gillian, Yandava, Chandri, Young, Sarah, Zhou, Shiguo, Zeng, Qiandong, Grigoriev, Igor V., Ma, Li-Jun, and Ciuffetti, Lynda M.
Abstract:: Pyrenophora tritici-repentis is a necrotrophic fungus causal to the disease tan spot of wheat, whose contribution to crop loss has increased significantly during the last few decades. Pathogenicity by this fungus is attributed to the production of host-selective toxins ( HST), which are recognized by their host in a genotype-specific...
