  • 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...

  • 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...

  • DNA fingerprinting and genome mapping in meadowfoam

    Creator:
    Katengam, Sureeporn
    Abstract:
    Marker information in the new oilseed crop, meadowfoam, is limited. Molecular markers to facilitate meadowfoam breeding and cultivar improvement are not available. The knowledge of genetic relationships among recent germplasm is not known. The objectives of this study were (i) to gain an understanding of genetic diversity and relationship patterns...

  • 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 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...
