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 ...
Prevalence, Diversity, and Management of Goss’s Leaf Blight (Clavibacter nebraskensis) in North Dakota
(North Dakota State University, 2018)
Goss’s wilt and leaf blight (GWLB) (Clavibacter nebraskensis) is a yield-limiting disease of corn (Zea mays L.). Research conducted in other corn growing states have indicated yield losses as severe as 60% on susceptible ...
Characterization of Sensitivity of Sclerotinia Sclerotiorum Isolates from North Central U.S. to Thiophanate-Methyl and Metconazole
(North Dakota State University, 2013)
Sclerotinia sclerotiorum (Lib.) de Bary causes Sclerotinia stem rot on canola and many other crops of economic importance in the U.S. SSR is primarily controlled with fungicides applied at flowering time. Most fungicides ...
Resistance to Septoria Musiva in Hybrid Poplar
(North Dakota State University, 2014)
Septoria leaf spot and stem canker, caused by the fungal pathogen Mycosphaerella
populorum Thompson (Anamomorph = Septoria musiva Peck). An efficient greenhouse disease
resistance screening is essential for the development ...
Inoculation and Spread of Dickeya in Potatoes
(North Dakota State University, 2019)
Field experiments were conducted in two different growing environments to evaluate the spread and movement of Dickeya dadantii. A procedure to inoculate seed potatoes with Dickeya dadantii was developed to use during this ...
