Multi-location wheat stripe rust QTL analysis: genetic background and epistatic interactions

Creator:: Vazquez, M. Dolores, Zemetra, Robert, Peterson, C. James, Chen, Xianming M., Heesacker, Adam, and Mundt, Christopher C.
Abstract:: Stripe rust is a foliar disease of wheat (Triticum aestivum L.) caused by the air-borne fungus Puccinia striiformis f. sp. tritici and is present in most regions around the world where commercial wheat is grown. Breeding for durable resistance to stripe rust continues to be a priority, but also is...

A whole-genome, radiation hybrid mapping resource of hexaploid wheat

Creator:: Tiwari, Vijay K., Heesacker, Adam, Riera-Lizarazu, Oscar, Gunn, Hilary, Wang, Shichen, Wang, Yi, Gu, Young Q., Paux, Etienne, Koo, Dal-Hoe, Kumar, Ajay, Luo, Ming-Cheng, Lazo, Gerard, Zemetra, Robert, Akhunov, Eduard, Friebe, Bernd, Poland, Jesse, Gill, Bikram S., Kianian, Shahryar, and Leonard, Jeffrey M.
Abstract:: Generating a contiguous, ordered reference sequence of a complex genome such as hexaploid wheat (2n = 6x = 42; approximately 17 GB) is a challenging task due to its large, highly repetitive, and allopolyploid genome. In wheat, ordering of whole-genome or hierarchical shotgun sequencing contigs is primarily based on recombination...

Single nucleotide polymorphism diversity in domesticated and wild sunflowers

Creator:: Freeman, Carrie
Abstract:: Single nucleotide polymorphisms (SNPs) are the most common DNA polymorphisms in plant and animal genomes. SNPs were identified in the allele sequences of up to 12 sunflower (Helianthus annuus L.) genotypes for a genome-wide sample of 81 loci originally mapped using restriction fragment length polymorphism (RFLP) markers. The RFLP loci...

Multi-location analysis for the identification of quantitative trait loci underlying disease resistance against Cephalosporium gramineum and Puccinia striiformis f. sp. tritici by linkage mapping in wheat (Triticum aestivum L.)

Creator:: Vazquez, Maria Dolores
Abstract:: Wheat (Triticum aestivum L.) is one of the major crops produced in the U.S. Pacific Northwest, a region known for its wheat production for international export. Wheat production in the region is threatened by diseases such as Cephalosporium stripe and stripe rust. Cephalosporium stripe is a vascular wilt disease of...

Host and Pathogen Genetics in the Sharp Eyespot Disease of Wheat

Creator:: Liu, Jiang
Abstract:: Wheat sharp eyespot (SES), caused by the soil-borne fungus Rhizoctonia cerealis is a common stem disease of wheat globally. The disease caused a severe and extensive epidemic throughout the Willamette Valley of Oregon in 2014 and has remained one of the most important wheat diseases in this region. However, litte...

Molecular mechanisms underlying the high oleic acid phenotype in sunflower

Creator:: Schuppert, Gunnar Felix
Abstract:: Wildtype sunflower typically produces 12-24% oleic acid (18:1) and 70-82% linoleic acid (18:2). High-oleic sunflower, by contrast, produces up to 80-94% oleic acid. The monounsaturated oleic acid has a greater oxidative stability than the polyunsaturated linoleic acid, predominant in wildtype sunflower, and has greater nutritional benefits than polyunsaturated and saturated...

Breeding tools for Cuphea : An updated genetic linkage map and fatty acid mutant candidate gene analysis

Creator:: Powers, Carol Anne
Abstract:: Medium chain fatty acids (MCFAs) are important industrial feedstocks for soaps, detergents and surfactants. Interspecific lines derived from Cuphea lanceolata and Cup hea viscosissima are being domesticated as a temperate source of MCFAs. These species also serve as model organisms for understanding the biosynthesis of MCFAs in seeds. Various markers...

Physiological, Chemical and Genetic Studies in Meadowfoam (Limnanthes alba)

Creator:: Zhang, Jun
Abstract:: Meadowfoam (Limnanthes alba) is an oilseed crop with unique chemical characteristics. The ability to identify physiological maturity (PM) and harvest maturity HM of the crop would permit timely harvest of high quality seeds. However, changes of oil contents, fatty acid profile and glucosinolate contents, as well as seed quality during...

Quantitative trait loci mapping of yield, its related traits, and spike morphology factors in winter wheat (Triticum aestivum L.)

Creator:: Gaynor, Robert C.
Abstract:: Increasing grain yield in wheat (Triticum aestivum L.) is a challenging task, because yield is a complex trait controlled by many genes and highly influenced by environmental factors. The genetic control of yield components and other traits associated with yield may be less complex and thus more manageable for breeding....

Genetic factors that provide adult plant resistance against Puccinia striiformis f. sp. tritici to wheat cultivar 'Stephens' in a multilocation analysis.

Creator:: Vazquez, Maria Dolores
Abstract:: Stripe rust (Puccinia striiformis f. sp. tritici) has been receiving increased attention in the USA since the appearance of more virulent races detected in the past decade. These races caused yield losses even in areas where the disease previously was rarely detected. Host plant resistance is the most cost effective...
