摘要: We have cloned two genes for gibberellin (GA) 2-oxidase from rice ( Oryza sativa L.). Expression of OsGA2ox2 was not observed. The other gene, OsGA2ox3, expressed in every tissue examined and enhanced by the application biologically active GA. Recombinant OsGA2ox3 protein catalyzed metabolism GA(1) to GA(8) GA(20) GA(29)-catabolite. These results indicate that is involved homeostatic regulation endogenous level GA rice.
