Characterization of Pea Seed-Borne Mosaic Virus, Efficacy of Foliar Applications for Common Bacterial Blight Management in Dry Beans and Impact of Common Bacterial Blight on Prostrate and Upright Beans
(North Dakota State University, 2018)
PSbMV in field pea has resulted in substantial yield and seed quality losses world-wide and has recently been reported in North Dakota. Traditional management of this virus includes preventative measures such as removal ...
Histology of Spot Blotch Infection in Barley, QTL Mapping of Resistance to Fusarium Head Blight, and Characterization of Root Rot Diseases in Wheat
(North Dakota State University, 2017)
Three independent studies were conducted for spot blotch (Bipolaris sorokiniana), Fusarium head blight (FHB) (Fusarium graminearum), and root rot diseases (Fusarium species and B. sorokiniana). Histopathology of compatible ...
The Effect of Substitution of Cytoplasmic Organelles on the Responses of Wheat to Foliar Pathogens
(North Dakota State University, 2016)
Parastagonospora nodorum and Pyrenophora tritici-repentis are foliar pathogens of wheat, capable of causing up to 50% yield losses, and reduced grain quantity and quality, by infecting wheat leaves and kernels. The most ...
Phenotypic Characterization of Leptosphaeria maculans Pathogenicity Groups Aggressiveness on Brassica napus
(North Dakota State University, 2015)
One of the most destructive pathogens of canola (Brassica napus L.) is Leptosphaeria maculans (Desm.) Ces. & De Not., which causes blackleg disease. This fungus produces strains with different virulence profiles (pathogenicity ...
Seed to Seedling Transmission of Colletotrichum lindemuthianum in Dry Edible Pinto Bean
(North Dakota State University, 2015)
Dry bean anthracnose, caused by Colletotrichum lindemuthianum, is a damaging disease that can cause significant reductions in seed quality and yield. The purpose of this study was to determine the races of C. lindemuthianum ...
Towards Identifying the Physical and Molecular Components Involved in Resistance to Leaf Rust Pathogen Puccinia Triticina in Wheat and Barley
(North Dakota State University, 2016)
Genetic resistance is the preferred method to reduce yield losses caused by many diseases including wheat leaf rust. However, in many cases host resistance seems to be short-lived. For decades, scientists have tried and ...
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, ...
