Understanding Programmed Cell Death Pathways by Characterizing Barley Disease Lesion Mimic Mutants
(North Dakota State University, 2021)Programmed cell death (PCD) in plants refers to rapid and localized cell death that occurs as a result of regular biological processes, or in response to infection or injury. Understanding the molecular mechanisms of PCD ... -
Molecular Mapping of QTL for Genetic Transformation-Related Trait and CRISPR/Cas9-Mediated Gene Editing in Wheat
(North Dakota State University, 2022)Plant transformation is a valuable tool for gene characterization and crop improvement. However, wheat transformation is greatly impacted by genotype dependency for successful regeneration of the transgenic plants. For ... -
Detection of Qol Fungicide Resistance and Genomic Analysis for Identification of Polyketide Synthases and Methyltransferases in Ascochyta rabiei
(North Dakota State University, 2011)Ascochyta blight is the most important disease of chickpeas in North America since the fungal pathogen Ascochyta rabiei was introduced to this region in 1986. Ascochyta blight epidemics can cause yield and economic losses ... -

(North Dakota State University, 2022)Barley spot form net blotch (SFNB) caused by Pyrenophora teres f. maculata (Ptm) and Fusarium head blight (FHB) caused by Fusarium graminearum are devastating diseases of barley requiring advanced molecular breeding tools ... -
Improving Management and Understanding of Major Diseases of Sugar Beet
(North Dakota State University, 2022)Sugar beet is a sugar-yielding crop, that contributes 25% of the global sucrose production. Economic production of sugar beet is hampered by Cercospora leaf spot (CLS) (Cercospora beticola), Rhizoctonia crown and root rot ... -
Managing Economically Important Diseases of Sunflower and Oilseed Rape in North Dakota, California, and Schleswig-Holstein
(North Dakota State University, 2021)Rust, caused by Puccinia helianthi, and blackleg, caused by Leptosphaeria maculans, are economically important diseases on sunflower and oilseed rape, respectively. In order to recommend the most effective disease management ... -
Fitness and Management of Site-specific Fungicide Resistant Cercospora beticola Isolates from Sugar Beet
(North Dakota State University, 2020)Cercospora leaf spot (CLS), caused by the fungal pathogen Cercospora beticola, is one of the most destructive foliar diseases on sugar beet. It severely affects productivity and profitability of the sugar beet industry. ... -
Plant-Parasitic Nematodes on Corn (Zea mays L.) and Soybean (Glycine max L.) in North Dakota
(North Dakota State University, 2020)Four studies were conducted to investigate plant-parasitic nematodes (PPN) of corn and soybean in ND. The first study investigated the incidence and abundance of vermiform PPN in ND corn fields in 2015 and 2016. Samples ... -
Cloning and Characterization of rcs5, Spot Blotch Resistance Gene and Pathogen Induced Nec3 Gene Involved in Programmed Cell Death in Barley
(North Dakota State University, 2019)Upon sensing pathogens, plants initiating defense responses typically resulting in programmed cell death (PCD). PCD effectively subdues biotrophic pathogens but is hijacked by necrotrophs that colonize the resulting dead ... -
Population Structure of Uromyces appendiculatus in North Dakota
(North Dakota State University, 2019)North Dakota is the lead producing state of common bean in the USA, accounting for 43% of national production. Bean rust is caused by the autoecious, macrocyclic fungus Uromyces appendiculatus (Pers.:Pers.). All pathogen ... -
Characterization of Pectobacterium carotovorum subsp. brasiliense as a Causal Agent of Sugarbeet Soft Rot
(North Dakota State University, 2018)A soft rot decay of sugarbeet was observed in commercial fields in North Dakota and Minnesota from 2012 to 2016. Symptoms reported are similar to those for bacterial vascular necrosis and rot caused by Pectobacterium ... -
