  • Long-chain trans-prenyl diphosphate synthase gene
    Patent number: 9127286
    Abstract: A method for increasing the amount of trans-1,4-polyisoprene contained in a plant, and a method for effectively producing trans-1,4-polyisoprene using a plant are provided. A long-chain trans-prenyl diphosphate synthase gene that comprises DNA having at least one base sequence selected from the group consisting of a base sequence from positions 88 to 1134 of the base sequence of SEQ ID NO: 1 or a complementary sequence thereof, a base sequence from positions 42 to 1088 of the base sequence of SEQ ID NO: 3 or a complementary sequence thereof, and a base sequence from positions 91 to 1140 of the base sequence of SEQ ID NO: 5 or a complementary sequence thereof are disclosed; as well as a plant transformed with an expression vector containing the gene.
    Type: Grant

    Assignee: Hitachi Zosen Corporation
    Inventors: Yoshihisa Nakazawa, Yoko Harada, Hirotaka Uefuji, Ren Chen, Takeshi Bamba, Akio Kobayashi, Eiichiro Fukusaki, Kazumasa Hirata, Koichiro Gyokusen
  • Homogentisic acid geranylgeranyl transerase polypeptide
    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.
