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...

Simple sequence repeat marker development and mapping in cultivated sunflower, Helianthus annuus L.

Creator:: Yu, Ju-Kyung
Abstract:: The cultivated sunflower (Helianthus annuus L., x=17) is one of the most important annual oilseed crops in the world. There are very few publicly shared sequence-based DNA markers and genetic maps in sunflower, even though molecular DNA markers and genetic maps have become widely used in all areas of genetic...

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...

The acetohydroxyacid synthase gene family its role in herbicide resistant sunflowers

Creator:: Hawley, Robin M.
Abstract:: Resistance to acetohydroxyacid synthase (AHAS)-inhibiting herbicides has been reported in over 90 weedy species, including wild sunflower biotypes, since the herbicides were developed in 1982. The AHAS gene family in sunflower, consisting of three paralogs AHAS1 , AHAS2, and AHAS3, has been targeted for inducing herbicide resistance. A polymorphism identified...

Genetics of tocopherol composition in sunflower seed

Creator:: Hass, Catherine G.
Abstract:: Tocopherols are plant secondary metabolites that are known collectively as vitamin E. Tocopherol compounds act as potent antioxidants by quenching free radicals and protecting fatty acids from oxidative damage. In humans (in vivo) tocopherols protect membrane lipids from breaking down, while in oils (in vitro) tocopherols protect fatty acids from...

Seed dormancy in domesticated and wild sunflowers (Helianthus annuus L.) :types, longevity and QTL discovery

Creator:: Brunick, Robert L.
Abstract:: Elite inbred sunflower (Helianthus annuus L.) lines were found to have short-lived embryo and seed covering dormancies. Seed dormancy of wild sunflowers (H. annuus, H. argophyllus and H. exilis) was found to be controlled primarily by the seed covering (seed coat and pericarp) and embryo dormancy was short-lived (four to...

The development and analysis of sequence-based DNA markers in sunflower for DNA fingerprinting and candidate gene analysis

Creator:: Hongtrakul, Vipa
Abstract:: Molecular DNA markers have become widely used in all areas of genetic research. The objectives of this thesis were to develop polymorphic markers in sunflower and utilize the markers for genetic and candidate gene analyses. Amplified fragment length polymorphism (AFLP) markers were used to estimate genetic similarities and assess the...

Marker development, genome mapping, and cloning of candidate disease resistance genes in sunflower, Helianthus annuus L

Creator:: Gedil, Melaku Ayele
Abstract:: The level of polymorphisms of many biochemical and DNA markers are low in cultivated sunflower (Helianthus annuus L.). The number of mapped public DNA markers is limited. Molecular markers have not been developed for the most important diseases of sunflower, such as downy mildew. The objectives of this study were...
