Scanning Electron Microscope Examination of Sugarbeet Flowers and Fruits Infected with Phoma Betae
(North Dakota State University, 1980)
There are three natural openings in a mature sugarbeet fruit which serve as avenues of entry for microorganisms: 1) the basal pore which contains dried parenchyma and vascular tissue and is the point where the flower was ...
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.). ...
Downy Mildew of Sunflowers: Establishment of Baseline Sensitivity to Azoxystrobin and Monitoring for the Development of Fungicide Resistance and Plasmopara Halstedii Virulence Phenotype Changes
(North Dakota State University, 2017)
Downy mildew, caused by Plasmopara halstedii (Farl.) Berl. and de Toni, is an economically important disease in cultivated sunflowers, Helianthus annuus L. The objectives of this study were to determine disease pressure ...
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 ...
Computational Identification, Phylogenetic and Synteny Analysis of Receptor-Like Kinases “RLK” and Receptor-Like Proteins “RLP” in Legumes
(North Dakota State University, 2018)
Legumes are considered the second most important family of crop plants after the grass family based on economic relevance. In recent years, the field of legume genomics has expanded due to advancements in high-throughput ...
Pre-Harvest Glyphosate Use During Wheat Cultivation: Effects on Wheat Chemistry and Human Gut Microbiota
(North Dakota State University, 2018)
Glyphosate is the most widely used herbicide in the world which is sometimes utilized as a pre-harvest desiccant during wheat cultivation. It inhibits the 5-enolpyruvylshikimate-3-phosphate synthase enzyme in the shikimic ...
Environmental Influence on Cold-Climate Grapevine (Vitis Spp.) Fall Acclimation Response and Fruit Ripening
(North Dakota State University, 2016)
Two experiments were conducted to determine differences in sensitivity to temperature among cold-climate grapevine genotypes in fall-acclimation response. One experiment utilized a growth chamber to compare grapevine ...
Genetic and Physiological Relationships between Oat Grain Quality Components
(North Dakota State University, 2013)
The use of oats for human consumption is increasing every day due to the health benefits of oat products. With the objective to study relationships among factors affecting oat grain quality, two Recombinant Inbred Lines ...
