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 ... -
Characterizing Pyrenophora Teres F. Maculata in the Northern United States and Impact of Spot Form Net Blotch on Yield of Barley
(North Dakota State University, 2015)Pyrenophora teres f. maculata causes spot form net blotch (SFNB) on barley and was recently documented in North Dakota. The impact of SFNB on barley, the genetic diversity of the pathogen, and virulence structure are unknown ... -
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 ... -
Comparative Population Genetics of Fusarium Graminearum and Novel Sources of Resistance to Fusarium Head Blight in Spring Wheat
(North Dakota State University, 2013)Fusarium graminearum is the major causal agent of Fusarium head blight (FHB) in cereal crops. The fungus produces several types of trichothecenes [Deoxynivalenol (DON) and its acetylated derivatives, 3-acetyldeoxynivalenol ... -
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 ... -
Developing Management Tools for Sunflower Rust (Puccinia Helianthi)
(North Dakota State University, 2013)Sunflower rust, caused by Puccinia helianthi (Schwein), is an economically important disease in North Dakota. Since 2008, sunflower rust incidence and severity have increased. Therefore, a four year study was initiated to ... -
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 ... -
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, ... -
