Evaluation of Genetic Resistance to Common Bacterial Blight in Dry Edible Bean
(North Dakota State University, 2015)
Common bacterial blight (CBB) is an economically important disease of dry bean worldwide caused by Xanthomonas axonopodis pv. phaseoli, (Xap). The objectives of this research were to determine the frequency of CBB resistance ...
Evaluating Chemical Seed Treatments for Fusarium Root Rot Control in Dry Beans and Field Peas
(North Dakota State University, 2014)
This study evaluated commercially available seed treatment products for their ability to control Fusarium solani and F. avenaceum, causal agents of root rot in dry edible bean and field peas, respectively, through in-vitro, ...
Revisiting Management Practices for Diseases of Spring Barley in North Dakota
(North Dakota State University, 2018)
Common barley diseases observed in North Dakota include net blotch, spot blotch, leaf and stripe rust, bacterial leaf streak, and Fusarium head blight. The first objective of this research was to determine the effect of ...
Expression Analysis of the Expanded Cercosporin Gene Cluster in Cercospora beticola
(North Dakota State University, 2018)
Cercospora leaf spot is an economically devastating disease of sugar beet caused by the fungus Cercospora beticola. It has been demonstrated recently that the C. beticola CTB cluster is larger than previously recognized ...
Characterization of Cytochrome B from European Field Isolates of Cercospora Beticola with Quinone Outside Inhibitor Resistance
(North Dakota State University, 2012)
Cercospora leaf spot (CLS), caused by the fungal pathogen Cercospora beticola, is the most important foliar disease of sugar beet worldwide. Control strategies for CLS rely heavily on fungicides including quinone outside ...
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 ...
Genomic Mapping of Leaf Rust and Stem Rust Resistance Loci in Durum Wheat and Use of RAD-Genotype by Sequencing for the Study of Population Genetics in Puccinia Titicina
(North Dakota State University, 2016)
Leaf rust, caused by Puccinia triticina Erikss. (Pt), and stem rust, caused by Puccinia graminis f. sp. tritici Erikss. and E. Henn (Pgt), are among the most devastating diseases of durum wheat (Triticum turgidum L. var. ...
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, ...
Identification of Quantitative Trait Loci for Resistance to Tan Spot in Durum Wheat
(North Dakota State University, 2018)
Tan spot, caused by Pyrenophora tritici-repentis (Ptr), is a major foliar disease on wheat. The pathosystem involves three pairs of necrotrophic effector (NE) and host sensitivity (S) gene interactions, namely Ptr ToxA-Tsn1, ...
Molecular Characterization and Pathogenicity of Sunflower Stem Pathogens
(North Dakota State University, 2014)
Sunflower (Helianthus annuus L.) production can be limited by several stem diseases.
Among these, Phomopsis stem canker causes frequent yield reductions in Australia, Europe and
North America. In the U.S., while Diaporthe ...
