Identification and Genomic Analysis of Stagonospora Nodorum Blotch Susceptibility Genes in Wheat
(North Dakota State University, 2014)Parastagonospora nodorum is a necrotrophic fungal pathogen that causes the disease Stagonospora nodorum blotch (SNB) on wheat. The fungus produces necrotrophic effectors (NEs), that when recognized by corresponding host ... -
Identification and Validation of a New Source of Low Grain Cadmium Accumulation in Durum Wheat (Triticum Turgidum L. Subsp. Durum (Defs.))
(North Dakota State University, 2017)Cadmium (Cd) is a toxic heavy metal with no known biological function. The maximum level of Cd concentration allowed in the international market for wheat grain is 0.2 mg kg-1. Higher Cd levels in durum wheat (Triticum ... -
Identification of Molecular Markers for Marker-Assisted Selection of Malting Quality and Associated Traits in Barley
(North Dakota State University, 2015)Barley (Hordeum vulgare L.) is one of the most important cereal crops in North Dakota, which ranks second amongst all states for barley production in the United States. Barley is used for the production of malt, which is ... -
Identification of Molecular Markers Linked to X-Disease Resistance in Chokecherry
(North Dakota State University, 2012)X-disease, caused by phytoplasmas, is one of the destructive diseases in stone fruit trees, causing yield loss and poor fruit quality. So far no effective methods are available to control X-disease. X-disease resistance ... -
Identification of Quantitative Trait Loci Associated with a Low Cadmium Uptake Gene in Durum Wheat (Triticum Turgidum L. Var. Durum)
(North Dakota State University, 2013)The main objective of durum wheat breeding is to identify lines that are low in Cadmium accumulation by using linkage mapping. 178 recombinant inbred lines (RILs) derived from across between Grenora × Haurani were used to ... -
Identifying Dry Bean Genotypes and Genomic Regions Associated with Root Rot Resistance with Emphasis on Fusarium Solani F. Sp Phaseoli
(North Dakota State University, 2016)Common bean (Phaseolus vulgaris L.) is the most produced legume in the U.S. and worldwide. Fusarium root rot (FRR) is a widespread soil-borne diseases causing up to 86% yield reduction in beans. Large-seeded cultivars are ... -
Mitochondrial Sequence Diversity Among Alloplasmic and Euplasmic Triticum Species
(North Dakota State University, 2013)Four mitochondrial genomes of Triticum species were sequenced and annotated: 1) (lo) durum mitochondrial genome, which is an alloplasmic line with Triticum longissimum(SS) cytoplasm and T. turgidum (AABB) nucleus, 2) T. ... -
Molecular and Genetic Characterization of Fusarium Head Blight Resistance in Durum Wheat
(North Dakota State University, 2015)Fusarium head blight (FHB) is a devastating fungal disease of both durum and common wheat. Multiple sources of FHB resistance have been found in common wheat, but not in durum wheat. Lack of effective FHB resistance sources ... -
Molecular Mapping of Fusarium Head Blight Resistance in Two Adapted Spring Wheat Cultivars
(North Dakota State University, 2015)Releasing bread wheat (Triticum aestivum) cultivars with resistance to Fusarium head blight (FHB) disease can be endangered by narrowing the variation in genetic sources. However, resistance to FHB rely on five different ... -
Nuclear-Cytoplasmic Interaction Analysis: A Critical Step for Wheat Germplasm Enhancement
(North Dakota State University, 2014)Wheat (Triticum aestivum) possesses the largest set of available alloplasmic lines in either the plant or animal kingdom. These alloplasmic lines consist of novel combinations of wheat cultivar nuclei and cytoplasm, derived ... -
Phytoremediation of Soils Contaminated by Oil and Gas Drilling and Production Operations Using Grass Species
(North Dakota State University, 2014)Soil contaminated by crude oil or drill cuttings poses a threat to ecosystem. The objective of this study was to test tolerance levels of grass species to drill cuttings and crude oil in seed germination and at the 5-leaf ... -
Productivity and Sustainability of Intercropping Systems in the Northern Great Plains
(North Dakota State University, 2017)The sustainability and productivity of cropping systems in the northern Great Plains is at risk because food, feed, and energy are produced mainly in very short crop rotations or monocultures. High input agriculture and ... -
QTL Analysis for Fusarium Head Blight Resistance in Tunisian-Derived Durum Wheat Populations
(North Dakota State University, 2014)Durum (2n=4x=28; AABB) wheat is the grain of choice for the production of high-quality pasta products. Fusarium spp. are causal pathogens for Fusarium Head Blight (FHB). Limited host resistance to this disease exists among ... -
Quantitative Genetic Analysis of 16 Maize Populations Adapted to the Northern U.S. Corn Belt
(North Dakota State University, 2013)Genetic diversity is essential for genome sequencing and a key contributor to increase frequency of favorable alleles for maize improvement. The objectives of this study were to determine the genetic components, assess the ... -
Quantitative Genetics of Drought Resistance in Early Maturing Maize (Zea Mays L)
(North Dakota State University, 2015)Drought stress is paramount in limiting worldwide maize (Zea mays L.) production and productivity. In addition, drought has limited expansion of maize production to marginal conditions in areas including western North ... -
Radiation Hybrid Fine Mapping of Two Fertility-Related Genes: Marking the Path to Wheat Hybrids
(North Dakota State University, 2012)Over one billion people, more than 1/9th of the global population, are undernourished. Feeding the ever increasing population has to be the most important goal of plant sciences. Since cultivated areas are not likely to ... -
Radiation Hybrid Mapping of Barley Chromosome 3H
(North Dakota State University, 2014)Assembly of the barley (Hordeum vulgare L.) genome requires high resolution maps for aligning contig-based physical maps along chromosomes. Genetic maps lack accurate information on the physical position of almost half of ... -
