transformed plant, transformed plant seed, methods of raising the level of alfatocotrienol, betatocotrienol or both in a plant, increasing the level of alpha or betatocotrienol in plants, improving the tissue quality of an animal, transformed seed or its by-products plant, isolated polynucleotides, polynucleotides, recombinant DNA construction, cell and plant or seed

摘要

Preparation and use of isolated nucleic acids useful in altering the oil phenotype of plants are described. Isolated nucleic acids and their encoded polypeptides are described that alter alpha- and beta-tocotrienol content in transformed seeds and oil obtained from the transformed seeds. Expression cassettes, host cells and transformed plants are described that contain the foregoing nucleic acids.
