Patent ID: 11041168

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.
