    摘要： Compositions comprising a modulated tocol content in a plant or plant part are provided. In specific embodiments, the compositions and methods of the invention modulate tocol content by modulating the level of a polypeptide having a LEC1-type B domain in combination with modulating the level of at least one other polypeptide involved in tocol biosynthesis. Plants, plant parts, grain, seed and oil having the modulated tocol level are also provided. Methods to enhance oxidative stress tolerance of a plant or plant part, increase shelf-life, enhance the nutritional value, and improve tissue quality are also provided.

    摘要： 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. The marker loci of the invention, and suitable fragments thereof, are useful in methods of the invention for manipulating oil and/or oleic acid content and/or oleic acid/lineolic acid ratio of a plant or plant part thereof, for marker-assisted selection of a plant, for example, a maize plant, or plant part thereof, having an increased oil content and/or increased oleic acid content and/or an increased oleic acid/linoleic acid ratio, and for marker-assisted breeding of the high oil and/or high oleic acid trait.

    摘要： Compositions and methods for modulating the production and characteristics of oil in a plant or plant part thereof are provided. Compositions of the invention are nucleotide constructs that provide for expression of transcriptional activators that increase lipid biosynthesis in a plant in combination with the inhibition or disruption of starch biosynthesis and/or starch storage, and optionally in combination with expression of another polynucleotide of interest. Compositions also include transformed plants, plant cells, plant tissues, and plant seeds comprising these nucleotide constructs. The methods of the invention comprise introducing a combination of polynucleotides into a plant, wherein the polynucleotides provide for increased lipid biosynthesis and disruption of starch biosynthesis and/or starch storage, and optionally alteration of fatty acid metabolism. The methods and constructs find use in alteration of oil phenotype in a plant or plant part thereof.
