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, ...
Effectors and Effector Delivery in Magnaporthe Oryzae
(North Dakota State University, 2016)
Rice blast, caused by the fungus Magnaporthe oryzae, is one of the most destructive rice diseases. All plant parts can be affected including leaves, leaf collars, necks, panicles, pedicels, and seeds. The disease symptoms ...
Plant-Parasitic Nematodes on Sugarbeet in North Dakota and Minnesota
(North Dakota State University, 2019)
Field surveys were conducted in the Red River Valley (RRV) of North Dakota and Minnesota during 2016 and 2017 to determine the incidence, abundance, and distribution of plant-parasitic nematodes (PPNs) on sugarbeet. ...
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, ...
Evaluation of Field Pea Varieties for Resistance to Fusarium Root Rot Pathogens
(North Dakota State University, 2017)
Fusarium root rot is one of the most important diseases of pulse crops, with numerous Fusarium spp. comprising the disease complex. Fusarium solani and F. avenaceum have been reported to be major pathogens in the pea root ...
Ellucidation of RPG4/RPG5-Mediated Resistance Against Wheat Stem Rust in Barley
(North Dakota State University, 2015)
Wheat stem rust, caused by Puccinia graminis f. sp. tritici (Pgt), is a major threat to barley and caused devastating reductions in yield and economic losses. The barley line Q21861 was identified as the best source of ...
Characteristics and Host Range of a Novel Fusarium Species Causing Yellowing Decline of Sugarbeet
(North Dakota State University, 2013)
In 2008, a novel and distinct Fusarium species was reported in west central Minnesota causing early-season yellowing and severe decline of sugarbeet. This study was conducted to (i) establish optimum conditions for fungal ...
16S Ribosomal RNA and Phylograms: Characterizing Student Reasoning to Learning Outcomes from the American Society for Microbiology Curriculum
(North Dakota State University, 2017)
The American Society for Microbiology (ASM) has established a suggested curriculum for introductory microbiology courses that includes a focus on evolution. However, no data is published to describe how proficiently students ...
Lung Mucosal Response to Repeated Inhalational Insults with Immunomodulatory Agents in a Murine Model of Fungal Asthma: Airway Epithelium Takes the Center Stage
(North Dakota State University, 2013)
Asthma is a debilitating disease of the lungs affecting 235 million people worldwide. Fungus-associated asthma leads to a particularly severe type of disease, and exposure to environmental fungi and their products is ...
Phenotypic and Genotypic Effects of FlhC Mediated Gene Regulation in Escherichia Coli O157:H7
(North Dakota State University, 2011)
Escherichia coli (E.coli) 0157:H7, a pathogen belonging to the enterohemorrhagic group of E.coli, has long been a concern to human health. The pathogen causes a myriad of symptoms in humans, ranging from diarrhea and malaise ...
