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.

Abstract: A plant cultivation method of the present invention includes the steps of: placing a plant under a condition at a pressure of not less than 1.5 atmospheres and not more than 10 atmospheres; and cultivating the plant. A plant cultivation device (1) includes: a cultivation chamber (10); and a compressor (20) which supplies compressed air into the cultivation chamber. A carry-in opening (30), which is provided on a side wall (16) of the cultivation chamber (10) so that a material is carried in/out to/from the cultivation chamber (10) via the carry-in opening (30), is provided with a cover (31) which has a shape that is hemispherical and protrudes toward an inside of the cultivation chamber (10). The cover (31) closes the carry-in opening (30) by being in contact, via a packing (32), with an inner surface of the side wall (16) surrounding the carry-in opening (30).

Abstract: The present invention provides a sulfonate compound including a structure represented by a general formula (I) below. In the formula (I), an atomic group A-O is an atomic group that forms a fluorescent compound upon cleavage of a covalent bond with a sulfonyl group. There may be one or plural atomic groups B—SO3— bound to an atomic group A. B is a ring substituted by one or plural electron-withdrawing groups. The electron-withdrawing group includes at least one selected from the group consisting of halogens, a carboxyl group, a carbamoyl group, a straight or branched alkylcarbamoyl group, a straight or branched alkanoyl group, a straight or branched alkoxycarbonyl group, a straight or branched alkyl halide group, and —NR3+ group (the three Rs each denote a hydrogen atom or a straight or branched alkyl group and may be the same or different). When there are plural Bs, the Bs may be the same or different.

Abstract: Disclosed is a process for producing an N-alkylimidazole which comprises reacting an imidazole with an N-alkylating agent in an organic solvent in the presence of alkali particles having a specific surface area of 0.6 M.sup.2 /g or larger.

Abstract: In producing formylimidazoles by catalytically oxidizing the corresponding 4- or 5-hydroxymethylimidazoles, the catalytic oxidation is carried out in the presence of a noble metal catalyst while oxygen or air is blown into the reaction system. In this case, it is particularly desirable that the catalytic oxidation in the presence of a noble metal catalyst be carried out in a solvent comprising an aqueous alkali or in a mixed solvent composed of an aqueous alkali and an organic solvent immiscible with water.

Abstract: A method of preparing an organ culture from branched tissue of a Catharanthus roseus seedling is disclosed. The indole alkaloids vincristine and vinblastine can be recovered from the organ culture tissue via extraction.

Abstract: A liquid crystal television receiver has a main frame including a reflecting plate and a hood member with a liquid crystal display panel and an electroluminescence panel. The reflecting plate is disposed so as to slant with respect to the liquid crystal display panel, and provides a display of a picture from the display panel in a reflecting manner. The electroluminescence panel is slidably provided in the hood member. For illuminating the liquid crystal display panel, the electroluminescence panel is slid above the liquid crystal display panel.
