Identification of Host Resistant Effective against the Barley Spot Form Net Blotch Pathogen
(North Dakota State University, 2014)
Spot form net blotch (SFNB) caused by Pyrenophora teres f. maculata is a major foliar disease of barley (Hordeum vulgare L.) worldwide. SFNB epidemics have recently been observed in major barley producing countries, ...
Genetically Dissecting the Recessive Rpg4-Mediated Wheat Stem Rust Resistance Locus in Barley
(North Dakota State University, 2014)
The rpg4-mediated resistance locus (RMRL) in barley provides recessive resistance against wheat stem rust (Puccinia graminis f. sp. tritici) races including the virulent race TTKSK (a.k.a Ug99). Three genes (HvAdfF3, Rpg5, ...
Physical and Chemical Treatments for Bacterial Biofilms
(North Dakota State University, 2014)
Physical and chemical treatments have been investigated for the treatment to remove biofilms. This thesis examines the problem of the removal and prevention of biofilms by: (i) using a water jet to determine biofilm stability ...
Gene Expression and Evolution in Escherichia Coli Biofilm
(North Dakota State University, 2014)
Biofilms can be defined as a complex aggregation of bacterial communities that involves many gene regulatory mechanisms, as well as evolutionary processes to increase biodiversity. Specific Aim 1 used a gene regulation ...
Characterization of a Novel Cryptosporidium Genotype in Red-Winged Black Birds
(North Dakota State University, 2014)
Cryptosporidium species cause cryptosporidiosis, characterized by acute gastroenteritis in humans and animals worldwide. Knowledge of the diversity of Cryptosporidium among mammals and birds is incomplete, especially in ...
Exploration of Laboratory Techniques Relating to Cryptosporidium Parvum Propagation, Life Cycle Observation, and Host Immune Responses to Infection
(North Dakota State University, 2014)
Cryptosporidium causes cryptosporidiosis, a self-limiting diarrheal disease in healthy people, but causes serious health issues for immunocompromised individuals. Cryptosporidiosis has been observed in humans since the ...
Role of ArcB/ArcA in the Regulation of Biofilm Formation in Escherichia coli in Conjunction with F1hD Expression
(North Dakota State University, 2014)
The two goals of this study were to identify the affect that arcB has on biofilm formation and to determine whether this was dependent on AckA. Acetyl phosphate is formed from acetyl-CoA during acetate metabolism and is ...
Evaluation of Winter Wheat Germplasm for Resistance to Stripe Rust and Leaf Rust
(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 ...
Evaluating Chemical Seed Treatments for Fusarium Root Rot Control in Dry Beans and Field Peas
(North Dakota State University, 2014)
This study evaluated commercially available seed treatment products for their ability to control Fusarium solani and F. avenaceum, causal agents of root rot in dry edible bean and field peas, respectively, through in-vitro, ...
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 ...
