Cloning and Characterization of rcs5, Spot Blotch Resistance Gene and Pathogen Induced Nec3 Gene Involved in Programmed Cell Death in Barley
(North Dakota State University, 2019)
Upon sensing pathogens, plants initiating defense responses typically resulting in programmed cell death (PCD). PCD effectively subdues biotrophic pathogens but is hijacked by necrotrophs that colonize the resulting dead ...
Genomic Mapping of Leaf Rust and Stem Rust Resistance Loci in Durum Wheat and Use of RAD-Genotype by Sequencing for the Study of Population Genetics in Puccinia Titicina
(North Dakota State University, 2016)
Leaf rust, caused by Puccinia triticina Erikss. (Pt), and stem rust, caused by Puccinia graminis f. sp. tritici Erikss. and E. Henn (Pgt), are among the most devastating diseases of durum wheat (Triticum turgidum L. var. ...
Dissecting the Mystery Behind the Rpg5 Mediated Puccinia graminis Resistance in Barley Using Genetics, Molecular and Bioinformatics Approaches
(North Dakota State University, 2017)
Barley rpg4/Rpg5 locus harbors three tightly linked genes, two NLRs Rpg5 and HvRga1, and HvAdf3, togather providing resistance against Puccinia graminis f. sp. tritici, causal agent of wheat stem rust including race TTKSK, ...
Molecular Characterization and Pathogenicity of Sunflower Stem Pathogens
(North Dakota State University, 2014)
Sunflower (Helianthus annuus L.) production can be limited by several stem diseases.
Among these, Phomopsis stem canker causes frequent yield reductions in Australia, Europe and
North America. In the U.S., while Diaporthe ...
Prevalence, Diversity, and Management of Goss’s Leaf Blight (Clavibacter nebraskensis) in North Dakota
(North Dakota State University, 2018)
Goss’s wilt and leaf blight (GWLB) (Clavibacter nebraskensis) is a yield-limiting disease of corn (Zea mays L.). Research conducted in other corn growing states have indicated yield losses as severe as 60% on susceptible ...
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 ...
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 ...
