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 ...
Studies on the Management of Potato Mop-Top Virus-Induced Tuber Necrosis
(North Dakota State University, 2015)
Tuber necrosis caused by the Potato Mop-top Virus (PMTV) has become one of the most important tuber necrosis diseases in the United States. PMTV is transmitted by the powdery scab pathogen (Spongospora subterranea f.sp ...
Studies on the Development and Management of Powdery Scab and Root Gall Formation Caused by Spongospora Subterranea on Potato (Solanum Tuberosum L.)
(North Dakota State University, 2015)
The biotroph protozoan Spongospora subterranea causes root gall formation and powdery scab on potato. Symptoms on tubers affect directly the quality and marketability of the harvested product while infection in roots are ...
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 ...
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, ...
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 ...
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 ...
