Abstract
The invention provides isolated nucleic acids and their encoded proteins that are involved in tocopherol or plastoquinone biosynthesis. The invention further provides recombinant expression cassettes, host cells, transgenic plants, and antibody compositions. The present invention provides methods and compositions relating to altering phytyl/prenyltransferase protein content and/or composition of plants.
Claims3
A method for increasing the level of tocopherol in a plant, comprising:
- (a) stably transforming a plant cell with a polynucleotide operably linked to a promoter, wherein the polynucleotide is selected from the group consisting of;
- i) a polynucleotide comprising the sequence set forth in SEQ ID NO:
- 3, and
- ii) a polynucleotlde that encodes the polypeptide of SEQ ID NO:
- 4,
- (b) growing the plant cell under plant growing conditions to produce a regenerated plant which expresses the polynucleotide for a time sufficient to increase the level of tocopherol in the plant.
