  • 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...

  • 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...

  • 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...

  • 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 fingerprinting in Cuphea lanceolata Ait. and C. viscosissima Jacq

    Creator:
    Karmarkar, Vidyadhar M.
    Abstract:
    Microsatellites or simple sequence repeats (SSRs) are highthroughput sequence based DNA markers that have been exploited as tools for measuring genetic distance and diversity in evolutionary studies, protection of intellectual property, genetic resource conservation management, cultivar identification and molecular breeding of crop plants. We isolated and sequenced 1095 clones from...

  • 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...

  • 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...

  • 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...

  • 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...
