Methods and compositions for modulating plant development are provided. Nucleotide sequences and amino acid sequences encoding Ovule Development Protein 2 (ODP2) proteins are provided. The sequences can be used in a variety of methods including modulating development, developmental pathways, altering oil content in a plant, increasing transformation efficiencies, modulating stress tolerance, and modulating the regenerative capacity of a plant. Transformed plants, plant cells, tissues, and seed are also provided.

Transgenic oilseeds having increased total fatty acid content of at least 10% and altered fatty acid profiles when compared to the total fatty acid content of null segregant oilseeds are described. Novel DGAT genes are used to achieve the increase in seed storage lipids.

DGAT genes for increased seed storage lipid production and altered fatty acid profiles in oilseed plants

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.

Producing maize plants having a high oil phenotype using a marker locus genetically linked with a QTL6 region

The preparation and use of nucleic acid fragments useful in altering the oil phenotype in plants are disclosed. Chimeric constructs incorporating such nucleic acid fragments and suitable regulatory sequences can be used to create transgenic plants having altered lipid profiles. Methods for altering the oil phenotype in plants using such nucleic acid fragments also are disclosed.

Alteration of oil traits in plants
