Abstract: The present application discloses an application of OsAO gene for improving rice resistance to rice stripe disease, rice black-streaked dwarf disease or other rice or corn virus diseases caused by homologous virus of rice black-streaked dwarf virus. The present application also provides an application of OsAO gene, the protein encoded by the gene or a recombinant vector containing the gene in regulating plant resistance to rice stripe disease, rice black-streaked dwarf disease or other rice and corn virus diseases caused by homologous virus of rice black-streaked dwarf virus, said protein has the amino acid sequence as shown in Seq 4. The experiment proved that the plant disease resistance is increased in rice overexpressing OsAO gene, indicating that the OsAO protein encoded by this gene plays an important role in rice resistance to rice stripe disease and rice black-streaked dwarf disease.

Abstract: A composition for use in preparation of carbon dioxide gel for external use of the present invention is used for preparing a carbon dioxide gel for external use including carbon dioxide dissolved therein in a substantial non-bubble form. The composition includes a granular material and a viscous material to be mixed with the granular material. In a first composition for use in preparation of carbon dioxide gel for external use, the granular material includes a weak acid and a calcium ion trapping agent as essential components, whereas the viscous material includes calcium carbonate, a gelling agent gelated by calcium ions and water as essential components. In a second composition for use in preparation of carbon dioxide gel for external use, the granular material includes a weak acid and a dispersant as essential components, whereas the viscous material includes calcium carbonate, a gelling agent gelated by calcium ions, a calcium ion trapping agent and water as essential components.
