Development of coenzyme Q10-enriched rice using sugary and shrunken mutants

Area of Science:

• Biotechnology
• Plant Science
• Nutritional Biochemistry

Background:

• Coenzyme Q10 (CoQ10) is a vital antioxidant and popular dietary supplement.
• Standard rice varieties primarily produce Coenzyme Q9, not the desired CoQ10.
• Previous research established the feasibility of producing CoQ10 in rice.

Purpose of the Study:

• To develop a more efficient method for CoQ10 production in rice.
• To increase the yield of CoQ10 in genetically modified rice plants.

Main Methods:

• Introduction of the decaprenyl diphosphate synthase gene into rice sugary and shrunken mutants.
• Cultivation and analysis of modified rice lines for CoQ10 content.

Main Results:

• The modified rice mutants efficiently produced Coenzyme Q10.
• CoQ10 yields in the engineered rice were 1.3 to 1.6 times higher than in previously enriched rice.
• The genetic modification strategy proved effective for enhanced CoQ10 biosynthesis.

Conclusions:

• Efficient CoQ10 production in rice is achievable through targeted gene introduction.
• This approach offers a promising strategy for biofortification of rice with CoQ10.
• Further development could lead to CoQ10-enriched rice as a sustainable food supplement source.
