(North Dakota State University, 2022)Puccinia graminis f. sp. tritici (Pgt) and Puccinia striiformis f. sp. tritici (Pst) are causal agents of devastating wheat stem and stripe rust diseases, respectively. Both diseases sporadically occur in North Dakota (ND), ... -
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 ... -
Development of Quantification and Diagnosis Methods for Cereal Bacterial Leaf Streak Pathogens
(North Dakota State University, 2022)Bacterial leaf streak (BLS) has been a major disease on wheat and barley in the Northern Great Plains. It is caused by Xanthomonas translucens pv. undulosa (Xtu) on wheat and X. translucens pv. translucens (Xtt) on barley. ... -
Characterization and Detection of Bacterial Pathogens of Common Bean
(North Dakota State University, 2022)Common bacterial blight (CBB) (Xanthomonas axonopodis pv. phaseoli (Xap) and X. fuscans pv. fuscans (Xff), halo blight (Pseudomonas savastanoi pv. phaseolicola (Psp)), and bacterial brown spot (P. syringae pv. syringae ... -
Genetic Characterization and Engineering of Disease Resistance to Spot Form Net Blotch and Fusarium Head Blight in Barley
(North Dakota State University, 2022)Barley spot form net blotch (SFNB) caused by Pyrenophora teres f. maculata (Ptm) and Fusarium head blight (FHB) caused by Fusarium graminearum are devastating diseases of barley requiring advanced molecular breeding tools ... -
Improving Management and Understanding of Major Diseases of Sugar Beet
(North Dakota State University, 2022)Sugar beet is a sugar-yielding crop, that contributes 25% of the global sucrose production. Economic production of sugar beet is hampered by Cercospora leaf spot (CLS) (Cercospora beticola), Rhizoctonia crown and root rot ... -
Identification and Characterization of Novel Cercospora beticola Necrosis-Inducing Effectors
(North Dakota State University, 2021)Cercospora beticola is a hemibiotrophic fungus responsible for Cercospora leaf spot disease of sugar beet (Beta vulgaris). Plant pathogens such as C. beticola utilize “effector” molecules to aid in disease establishment. ... -
Improving Disease Management in Field Pea and Durum Wheat in the MonDak Region
(North Dakota State University, 2021)Results from wilt pathogenicity and race evaluations for 25 North Dakota Fusarium oxysporum f.sp. pisi (Fop) isolates conducted in the greenhouse indicated all Fop races exist in North Dakota. Race 2 isolates were more ... -
