From Bioinformatics to Identifying R-genes, Enhancers, Signaling Pathways and Pathogen Elicitors in the Barley-Stem Rust Pathosystem
(North Dakota State University, 2018)
Stem rust, caused by Puccinia graminis f. sp. tritici (Pgt) is a threat to wheat and barley. Rpg1 is the only deployed stem rust resistance gene in barley that provides resistance to the predominant races in North America, ...
Identification and Functional Characterization of Necrotrophic Effectors in Parastagonospora Nodorum
(North Dakota State University, 2015)
The necrotrophic fungus Parastagonospora nodorum (teleomorph; Phaeosphaeria
nodorum), is the causal agent of Septoria nodorum blotch (SNB) on common wheat (Triticum
aestivum L.) and durum wheat (Triticum turgidum L.). ...
Characterization and Identification of Genetic Resistance to Puccinia Graminis F. Sp. Tritici in Triticum Aestivum and Hordeum Vulgare
(North Dakota State University, 2015)
Wheat stem rust, caused by Puccinia graminis f. sp. tritici (Pgt), is a major threat to wheat (Triticum aestivum) and barley (Hordeum vulgare) production. The emergence of the highly virulent Ug99-lineage stem rust races ...
Molecular Genetic Characterization of Ptr ToxC-Tsc1 Interaction and Comparative Genomics of Pyrenophora tritici-repentis
(North Dakota State University, 2018)
Tan spot of wheat, caused by Pyrenophora tritici-repentis, is an economically important disease worldwide. The disease system is known to involve three pairs of interactions between fungal-produced necrotrophic effectors ...
Molecular and Histological Study of Sphaerulina musiva-Populus spp. Interaction
(North Dakota State University, 2017)
Sphaerulina musiva, the causal agent of leaf spot and stem canker, is responsible for critical yield loss of hybrid poplar in agroforestry. This research examined quantification of S. musiva in host tissue, and infection ...
Identification of Brassica Napus L. Sources of Resistance Against Blackleg (Leptosphaeria Maculans)
(North Dakota State University, 2017)
Blackleg, caused by the fungus Leptosphaeria maculans (Desm.) Ces. et de Not. [anamorph = Phoma lingam (Tode: Fr.) Desm.] has become the most important disease affecting canola around the world. A study was conducted to ...
Parasitic Fitness of SDHI-Sensitive and -Resistant Isolates of Alternaria Solani
(North Dakota State University, 2017)
Early blight of potato (Solanum tuberosum L.) is caused by Alternaria solani Sorauer. The single-site mode of action chemistries of the succinate dehydrogenase inhibitors (SDHIs) and quinone outside inhibitors (QoIs) have ...
Development of Management Tools for Sunflower Downy Mildew (Plasmopara Halstedii) and Rust (Puccinia Helianthi)
(North Dakota State University, 2016)
Downy mildew (Plasmopara halstedii) and rust (Puccinia helianthi) are two economically important diseases of sunflower (Helianthus annuus) in North Dakota. Both diseases are capable of causing significant reductions in ...
Identification and Characterization of Pythium Spp. on Glycine Max (Soybean) in North Dakota
(North Dakota State University, 2013)
The Oomycete Pythium comprises one of the most important groups of seedling pathogens affecting soybean, causing both pre- and post-emergence damping off. Numerous species of Pythium have been identified and found to be ...
Identification of Quantitative Trait Loci (QTL) Associated with Resistance to Initial Infection of Fusarium Head Blight in Spring Wheat
(North Dakota State University, 2017)
Video summarizing a Ph.D. dissertation for a non-specialist audience.
