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.
