(North Dakota State University, 2013)Blackleg, caused by Leptosphaeria maculans is one of the most devastating diseases of canola (Brassica napus) in North Dakota. A study was conducted to characterize prevalence of pathogenicity groups (PG), identify population ... -
Genetically Dissecting the Recessive Rpg4-Mediated Wheat Stem Rust Resistance Locus in Barley
(North Dakota State University, 2014)The rpg4-mediated resistance locus (RMRL) in barley provides recessive resistance against wheat stem rust (Puccinia graminis f. sp. tritici) races including the virulent race TTKSK (a.k.a Ug99). Three genes (HvAdfF3, Rpg5, ... -
Genetics of the Host-Pathogen Interaction in the Barley-Net Form Net Blotch System
(North Dakota State University, 2017)Pyrenophora teres f. teres is a fungal pathogen that causes barley net form net blotch. To evaluate the genetics of resistance in barley, a RIL population was developed using resistant barley lines CI5791 and Tifang and ... -
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. ... -
Genomics and Management of Fusarium Root Rot of Field Peas
(North Dakota State University, 2012)Dry Pea or field pea (Pisum sativum L.) is an important cool season legume crop grown in the United States. Field peas are vulnerable to many diseases of which, soil borne diseases including wilt and root rot are of major ... -
Histology of Spot Blotch Infection in Barley, QTL Mapping of Resistance to Fusarium Head Blight, and Characterization of Root Rot Diseases in Wheat
(North Dakota State University, 2017)Three independent studies were conducted for spot blotch (Bipolaris sorokiniana), Fusarium head blight (FHB) (Fusarium graminearum), and root rot diseases (Fusarium species and B. sorokiniana). Histopathology of compatible ... -
Identification and Characterization of Novel Cercospora beticola Necrosis-Inducing Effectors
