  • Patent number: 8372616
    Abstract: It is a subject of this invention to isolate a gene group of enzymes involved in the biosynthesis of vitamin E of Para rubber tree, and to determine the base sequence of each gene. According to this invention, genes encoding enzymes involved in the vitamin E biosynthesis were isolated from Para rubber tree and the base sequences of these genes were determined. Since vitamin E is an antioxidant existing in nature, it is expected that transformation of a plant by using the genes obtained in the invention would result in an increase in the vitamin E content of the plant and, in its turn, contribute to the prevention of rubber from aging.
