  • Patent number: 8319010
    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.

  • Publication number: 20110099665
    Abstract: The present invention provides LEC1 variants. The LEC1 variants comprise a LEC1 A domain, a LEC1 B domain and a LEC1 C domain, where the LEC1 B domain has at least one mutation and/or is chimeric with respect to the LEC1 A or C domain. The invention also includes methods of preparing such LEC1 variants, and methods of using such LEC1 variants to modulate the level or activity of LEC1 variants in a plant cell. Modulation of LEC1 activity or levels can be used for different purposes such as increasing transformation efficiency, stimulating growth of somatic embryos, improving the growth and recovery of transformants, inducing apomixes, increasing transformation frequency, enhancing tissue culture response and the like.
