Development of Management Tools for Sunflower Downy Mildew (Plasmopara Halstedii) and Rust (Puccinia Helianthi)
(North Dakota State University, 2016)Downy mildew (Plasmopara halstedii) and rust (Puccinia helianthi) are two economically important diseases of sunflower (Helianthus annuus) in North Dakota. Both diseases are capable of causing significant reductions in ... -
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 ... -
Characterization of Fusarium Head Blight Resistance in Wheat
(North Dakota State University, 2017)Fusarium head blight (FHB) is a devastating fungal disease threatening wheat production worldwide. Utilization of resistant wheat cultivars is generally considered as the most effective, economic and environmental friendly ... -
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, ... -
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 ... -
Molecular and Histological Study of Sphaerulina musiva-Populus spp. Interaction
(North Dakota State University, 2017)Sphaerulina musiva, the causal agent of leaf spot and stem canker, is responsible for critical yield loss of hybrid poplar in agroforestry. This research examined quantification of S. musiva in host tissue, and infection ... -
Identification of Brassica Napus L. Sources of Resistance Against Blackleg (Leptosphaeria Maculans)
(North Dakota State University, 2017)Blackleg, caused by the fungus Leptosphaeria maculans (Desm.) Ces. et de Not. [anamorph = Phoma lingam (Tode: Fr.) Desm.] has become the most important disease affecting canola around the world. A study was conducted to ... -
Parasitic Fitness of SDHI-Sensitive and -Resistant Isolates of Alternaria Solani
(North Dakota State University, 2017)Early blight of potato (Solanum tuberosum L.) is caused by Alternaria solani Sorauer. The single-site mode of action chemistries of the succinate dehydrogenase inhibitors (SDHIs) and quinone outside inhibitors (QoIs) have ... -
