Abstract: The present invention relates to isolated polynucleotides or polypeptides that lead to improved plant oil yields. Disclosed herein is an isolated polynucleotide encoding a polypeptide that is distinguished from a wild-type Wrinkledt polypeptide by at least one amino acid substitution in the wild-type Wrinkledt amino acid sequence. In an embodiment, the at least one amino acid substitution comprises an amino acid substitution at a position corresponding to position 74 as set forth in SEQ ID NO: 1. In another embodiment, the substitution at position 74 is an amino acid substitution to a positively charged residue, wherein the positively charged residue is arginine or lysine.

Abstract: The application describes stabilized WRINKLED1 transcription factors, as well as nucleic acids, and expression cassettes that encode and express such stabilized WRINKLED1 transcription factors and that are useful for increasing production of oils in plants and seeds.

Abstract: The application describes plants, plant cells, and seeds that express WRINKLED1 transcription factors and/or 14-3-3 proteins that are useful for increasing production of oils in plants and seeds. Also described are expression systems and cassettes that encode and express such WRINKLED1 transcription factors and/or 14-3-3 proteins.
