(North Dakota State University, 2014)Wheat leaf rust, caused by Puccinia triticina (Pt), and wheat stripe rust caused by P. striiformis f. sp. tritici (Pst) are important foliar diseases of wheat (Triticum aestivum L.) worldwide. Breeding for disease resistance ... -
Expression Analysis of the Expanded Cercosporin Gene Cluster in Cercospora beticola
(North Dakota State University, 2018)Cercospora leaf spot is an economically devastating disease of sugar beet caused by the fungus Cercospora beticola. It has been demonstrated recently that the C. beticola CTB cluster is larger than previously recognized ... -
Fitness and Management of Site-specific Fungicide Resistant Cercospora beticola Isolates from Sugar Beet
(North Dakota State University, 2020)Cercospora leaf spot (CLS), caused by the fungal pathogen Cercospora beticola, is one of the most destructive foliar diseases on sugar beet. It severely affects productivity and profitability of the sugar beet industry. ... -
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, ... -
Genetic and Molecular Characterization of Genes Involved in Barley-Cochliobolus Sativus Interaction
(North Dakota State University, 2015)Spot blotch caused by ascomycete fungus Cochliobolus sativus (Ito & Kurib.) Drechs. ex Dastur. [anamorph: Bipolaris sorokiniana (Sacc.) Shoem.] is one of the most common and economically important diseases on barley. To ... -
Genetic and Molecular Characterization of Host Resistance and Susceptibility to Pyrenophora Teres F. Teres in Hordeum vulgare
(North Dakota State University, 2016)Pyrenophora teres f. teres, a necrotrophic fungal pathogen and causal agent of net form net blotch (NFNB), is an economically important pathogen of barley (Hordeum vulgare) and has potential to cause significant yield ... -
Genetic Characterization and Engineering of Disease Resistance to Spot Form Net Blotch and Fusarium Head Blight in Barley
(North Dakota State University, 2022)Barley spot form net blotch (SFNB) caused by Pyrenophora teres f. maculata (Ptm) and Fusarium head blight (FHB) caused by Fusarium graminearum are devastating diseases of barley requiring advanced molecular breeding tools ... -
Genetic Mapping and Characterization of Net Blotch Dominant Resistance and Dominant Susceptibility Loci in Barley
(North Dakota State University, 2017)Net blotch is an economically important foliar disease of barley that occurs in two distinct forms: Spot Form Net blotch (SFNB) and Net Form Net Blotch (NFNB) caused by the necrotrophic fungal pathogens Pyrenophora teres ... -
