A group of researchers from the Chinese Academy of Sciences (CAS) developed a genetically modified variety of rice capable of producing coenzyme Q10 (CoQ10), a key antioxidant in cellular energy generation and cardiovascular health. This molecule, present in foods such as meat and fish, is usually found at reduced levels in people with heart diseases.
The discovery, published days ago in the journal Cell, is based on the modification of five amino acids in the Coq1 enzyme, responsible for CoQ10 synthesis. Thanks to this intervention, scientists managed to make rice produce CoQ10 instead of CoQ9, a less effective variant that is naturally found in cereals.
CoQ10-enriched rice could become a new option to complement the diet with this beneficial compound. Xu Jingjing, a researcher at the Center of Excellence for Molecular Plant Sciences (CEMPS), stated that the concentration achieved in the modified grain is approximately 5 micrograms per gram, a quantity comparable to that of some antioxidant-rich vegetables.
“The CoQ10 content in this rice is similar to certain plant-based foods, making it a viable alternative to improve the intake of this compound in the daily diet,” explained Xu. Additionally, the researchers assured that genetic modification did not affect crop yield, which would facilitate its large-scale production without altering the agronomic characteristics of rice.
Genetic Editing and Its Potential in Food
To make rice naturally produce CoQ10, the team used a primary genetic editing technique that allows modifying specific genes without introducing external material. After analyzing more than 1,000 plant species, they identified the evolutionary changes that led certain crops to synthesize CoQ9 instead of CoQ10.
By correcting this difference in the structure of the Coq1 enzyme, scientists succeeded in having the plant generate CoQ10 without affecting its development. According to the researchers, this technology could be applied to other crops such as wheat, corn, and spinach, expanding the availability of this compound in food and offering a potential cardiovascular health benefit globally.
What are the health benefits of rice?
Rice is a nutritious cereal that provides energy, vitamins, minerals, and fiber. Its consumption can help improve metabolism, strengthen the immune system, and prevent diseases.
Its benefits
- Energy: Rice is rich in complex carbohydrates that provide energy for daily activities.
- Fiber: It is rich in fiber, which promotes nutrient absorption and prevents constipation.
- Immune system: Rice is a source of vitamins and minerals that benefit the immune system.
- Metabolism: It is an excellent source of vitamins and minerals that provide the foundation for body metabolism.
- Blood pressure: Rice is low in sodium and contains potassium, which promotes stable blood pressure.
- Cardiovascular system: It is low in sodium and cholesterol, promoting stable blood pressure and heart rate control.
Rice can be part of a weight loss plan if consumed properly. The key is to moderate portions and accompany it with lean proteins and vegetables.
