Abstract:
1. A method for increasing the ratio of lipids to proteins in oilseed crop seeds, comprising: (1) Cloning DNA encoding phosphoenolpyruvate carboxylase (PEPCase) or a PEPCase fragment, wherein the DNA encoding PEPCase or the PEPCase fragment is selected from the group consisting of a full length of the DNA encoding PEPCase, a 3′ or 5′ UTR of the DNA, introns of the DNA, or coding sequences of the DNA; (2) Constructing an antigene (Anti-PEP) from the clone of step (1); (3) Transforming a desired plant with a construct consisting essentially of: (4) Regenerating the transformed plant; and (5) Harvesting oilseed crop seeds comprising an increased ratio of lipids to proteins.
