Use of genes for increasing the oil content in plants
First Claim
1. A method of increasing the total oil content in a plant organism or a tissue, organ, part, cell or propagation material thereof, comprising a) transgenically expressing an oil synthesis enhancing protein in a starting plant organism or in a starting tissue, organ, part, cell or propagation material thereof so that a transgenic plant organism or a transgenic tissue, organ, part, cell or propagation material thereof is obtained, and b) selecting said transgenic plant organism or said transgenic tissue, organ, part, cell or propagation material thereof in which the total oil content is increased by contrasting to or comparing with said starting plant organism or said starting tissue, organ, part, cell or propagation material thereof.

Abstract
The invention relates to methods for increasing the oil content in plants, preferably in plant seeds, by expressing the Ypr140w polypeptide from yeast or corresponding polypeptides from plants. The invention furthermore relates to expression constructs for expressing the yeast polypeptide Ypr140w or corresponding polypeptides from plants in plants, preferably in plant seeds, the transgenic plants expressing the polypeptide and to the use of said transgenic plants for the production of food, feed, seed, pharmaceuticals or fine chemicals, in particular for the production of oils.

5. An expression cassette comprising in combination with a regulatory sequences a nucleic acid sequence selected from the group consisting of:
-
a) a nucleic acid sequence comprising a nucleotide sequence which is at least 60% identical to the nucleotide sequence of SEQ ID NO;
1, SEQ ID NO;
3 or SEQ ID NO;
5,b) a nucleic acid sequence comprising a fragment of at least 30 nucleotides of a nucleic acid sequence comprising the nucleotide sequence of SEQ ID NO;
1, SEQ ID NO;
3 or SEQ ID NO;
5,c) a nucleic acid sequence which encodes a polypeptide comprising an amino acid sequence at least about 60% identical to the amino acid sequence of SEQ ID NO;
2, SEQ ID NO;
4 or SEQ ID NO;
6, ord) a nucleic acid sequence which encodes a fragment of a polypeptide comprising the amino acid sequence of SEQ ID NO;
2, SEQ ID NO;
4 or SEQ ID NO;
6 wherein the fragment comprises at least 10 contiguous amino acid residues of the amino acid sequence of SEQ ID NO;
2, SEQ ID NO;
4 or SEQ ID NO;
6wherein said regulatory sequence is capable of mediating expression of said nucleic acid sequence in a plant. - View Dependent Claims (6, 7, 8, 9, 11)
