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