  • Publication number: 20160153007
    Abstract: The present invention provides a method of increasing production of amorpha-4,11-diene and a method of increasing production of natural rubber. The present invention relates to a method of increasing production of amorpha-4,11-diene which includes the step of attaching an enzyme inhibitor to Arabidopsis thaliana into which has been introduced a gene encoding amorphadiene synthase. The enzyme inhibitor inhibits at least one enzyme other than amorphadiene synthase, that catalyzes an enzymatic reaction in which farnesyl diphosphate acts as a substrate. The present invention also relates to a method of increasing production of natural rubber which includes the step of attaching an enzyme inhibitor to a rubber-producing plant. The enzyme inhibitor inhibits at least one enzyme other than enzymes involved in natural rubber synthesis, that catalyzes an enzymatic reaction in which farnesyl diphosphate acts as a substrate.

  • Publication number: 20140319001
    Abstract: A glass roll includes a glass film formed by a downdraw method. The glass film is wound into a roll using a winding roller in a state in which front and back glass surfaces of the glass film formed in the forming operation are exposed, and during the winding operation, the glass film is superposed on a separable protective sheet. The protective sheet extends beyond both sides in a width direction of the glass film. The protective sheet can further be wound on an outer peripheral surface of the glass film by winding only the protective sheet from a trailing end of the glass film in a winding direction of the glass film.
