  • 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...

  • 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...
