  • Genetics of low erucic acid and cytological analyses of wide hybrids in meadowfoam

    Creator:
    Gandhi, Sonali Dilip
    Abstract:
    Cultivated meadowfoam (Limnanthes alba Benth.) is an annual oil seed crop native to southern Oregon. California and British Columbia. The genus Limnanthes is composed of nine species and divided into two sections, Inflexae and Reflexae. The seed oil of meadowfoam is a rich source of erucic acid and several novel...

  • 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...

  • 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...

  • 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...

  • 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...

  • Mapping quantitative trait loci underlying genome-wide recombination rate and mating system differences in meadowfoam

    Creator:
    Kishore, Venkata Krishna
    Abstract:
    Meadowfoam (Limnanthes alba Bentham; Order: Brassicales; Family: Limnanthaceae) is a self-compatible, predominantly allogamous, insect pollinated species. Meadowfoam oil is a source of novel unsaturated very-long-chain (VLC) seed oils (C₂₀ and C₂₂) with low concentrations of saturated fatty acids (typically less than 2%) and outstanding oxidative stability. Here we report the...
