  • Patent number: 9137957
    Abstract: Compositions related to the quantitative trait locus 6 (QTL6) in maize and methods for their use are provided. The compositions are novel molecular marker loci that are genetically linked with QTL6 and which are associated with increased oil content and/or increased oleic acid content and/or an increased oleic acid/linoleic acid ratio of a plant or plant part thereof. These novel markers are characterized by the presence of at least one polymorphism relative to the corresponding marker locus from the QTL6 region of non-high-oil, non-high-oleic acid maize plants. In some embodiments, the novel marker loci comprise coding sequence for a maize DGAT1-2 polypeptide or biologically active variant thereof.

  • Patent number: 5566789
    Abstract: An improvement for brake systems that use a Bowden cable mechanism whereby the actuating force applied by a user is opposed and limited to a predetermined magnitude to avoid locking the rim of the wheel. The improvement includes the use of a spring member between the sheating and the adjusting nut. The spring can be either linear or non-linear. The action applied by a user to a brake system and transmitted to a brake caliper.
