| 20100017917 | TRANSGENIC PLANTS WITH TOCOPHEROL METHYLTRANSFERASE - Disclosed is are gene sequences encoding γ-tocopherol methyltransferases from photosynthetic organisms. The enzyme γ-tocopherol methyltransferase catalyzes the methylation of γ-tocopherol to yield α-tocopherol, the most bioactive species of tocopherol. γ-tocopherol methyltransferase is believed to be involved in regulating the relative amounts of the various tocopherols present in photosynthetic organisms. By introducing a genetic construct having a γ-tocopherol methyltransferase coding sequence placed under the control of a plant promoter into a plant, transgenic plants can be made having altered γ-tocopherol methyltransferase expression, to effect dramatic changes in the tocopherol profile of the plant. Transgenic plants can be made that have α-tocopherol as the predominant tocopherol in their seeds and oils. | 01-21-2010 |
