Generation of plants with altered oil content
The present invention is directed to isolated HI041 nucleic acid and protein, and to plants that display an altered oil content phenotype due to altered expression of a HI041 nucleic acid. The invention is further directed to methods of generating plants with an altered oil content phenotype.
1. A method of producing oil comprising:
introducing into progenitor cells of the plant a plant transformation vector comprising a nucleotide sequence that encodes a HIO41 polypeptide comprising the amino acid sequence set forth as SEQ ID NO:2, or an amino acid sequence having at least 95% sequence identity to the amino acid sequence set forth as SEQ ID NO:2;
growing the transformed progenitor cells to produce a transgenic plant, wherein said polynucleotide sequence is expressed;
identifying the transgenic plant that exhibits a high oil phenotype relative to a plant of the same species not comprising the plant transformation vector; and
recovering oil from said transgenic plant.
2. The method of claim 1 , wherein the oil is recovered from a seed of the plant.
3. A method of producing a plant having a high oil phenotype, said method comprising:
introducing into progenitor cells of the plant a plant transformation vector comprising a nucleotide sequence that encodes a HIO41 polypeptide comprising the amino acid sequence set forth as SEQ ID NO:2, or an amino acid sequence having at least 95% sequence identity to the amino acid sequence set forth as SEQ ID NO:2;
growing the transformed progenitor cells to produce a transgenic plant, wherein said polynucleotide sequence is expressed; and
identifying the transgenic plant that exhibits a high oil phenotype relative to a plant of the same species not comprising the plant transformation vector.
4. The method of claim 3 , wherein the nucleotide sequence encodes a HIO41 polypeptide having an amino acid sequence having at least 95% sequence identity to the amino acid sequence of SEQ ID NO:2.
5. The method of claim 4 , wherein the nucleotide sequence encodes a HIO41 polypeptide having the amino acid sequence set forth as SEQ ID NO:2.
6. The method of claim 5 wherein the nucleotide sequence encodes a HIO41 polypeptide consisting of the amino acid sequence set forth as SEQ ID NO: 2.
