A composition comprising the nucleotide sequence SEQ ID NO:
- 3.
A composition comprising the amino acid sequence SEQ ID NO:
- 4.
A composition comprising the nucleotide sequence SEQ ID NO:
- 3 or the amino acid sequence SEQ ID NO:
- 4 that results in diminished trigalactosyldiacylglycerol-5 (TGD5) protein function or activity as compared to an otherwise identical plant.
A method for increasing production and retention of oil in vegetative tissues of a plant, the method comprising:
- providing a plant comprising:
- a) the nucleotide sequence SEQ ID NO:
- 3 or the amino acid sequence SEQ ID NO:
- 4, and further comprising b) increased expression levels of a gene encoding phospholipid:diacylglycerol acyltransferase (PDAT), and c) increased expression levels of a gene encoding oleosin (OLE);
- and growing said plant to accumulate oil in vegetative tissues of said plant.
A method for enhancing the caloric content of vegetative tissue of a plant comprising:
- providing a plant comprising the nucleotide sequence SEQ ID NO:
- 3 or the amino acid sequence SEQ ID NO:
- 4;
- and growing said plant to accumulate in vegetative tissues of said plant.
A method for enhancing the caloric content of vegetative tissue of a plant comprising:
- providing a plant comprising the nucleotide sequence SEQ ID NO:
- 3 or the amino acid sequence SEQ ID NO:
- 4 and further comprising a defective sugar-dependent1 TAG lipase (sdp1) gene;
- and growing said plant to accumulate oil in vegetative tissues of said plant.
