  • Gene flow from transgenic glyphosate-resistant creeping bentgrass (Agrostis stolonifera L.) at the landscape level

    Creator:
    Zapiola, Maria Luz
    Abstract:
    Creeping bentgrass (Agrostis stolonifera L.) is an outcrossing, small- seeded, perennial grass that can establish outside of cultivation and has several compatible relatives. Glyphosate is a nonselective, broad spectrum, herbicide. Transgenic glyphosate-resistant (GR) creeping bentgrass (GRCB) was developed by The Scotts Company and Monsanto, but is still under USDA-APHIS regulated...

  • Exploiting Hordeum vulgare subsp. spontaneum genetic resources : diversity analysis and germplasm development

    Creator:
    Matus, Iván Ariel
    Abstract:
    Wild barley (Hordeum vulgare subsp. spontaneum) could be a source of useful genes for improving cultivated barley. The useful genes present in Hordeum vulgare subsp. spontaneum may be new alleles at described loci, or these may be entirely new genes in the sense that there is limited allelic variation at...

  • Stripe rust resistance pyramids in barley

    Creator:
    Castro Tabo, Ariel Julio
    Abstract:
    Genetic resistance is the most appropriate way to control diseases in crop plants. Resistance can be described as qualitative (involving a gene-for-gene system) or quantitative (with continuous distribution of disease levels). The relationships between different types of resistance remain obscure, as does the genetics of quantitative traits. The use of...

  • 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...
