Abstract

Coenzyme Q10 (CoQ10) is a popular food supplement. Earlier, we successfully produced CoQ10 in rice, which normally produces predominately CoQ9. Here we developed efficient production of CoQ10 in rice by introducing the gene for decaprenyl diphosphate synthase into rice sugary and shrunken mutants. These rices produced 1.3 to 1.6 times as much CoQ10 as the earlier enriched rice did.
