Summary:
- Researchers at the John Innes Centre have successfully biofortified tomatoes to contain high levels of Vitamin D3, a nutrient typically found in animal products.
- The study utilizes CRISPR-Cas9 gene editing to suppress a specific enzyme (Sl7-DR2) in the tomato plant, which allows provitamin D3 to accumulate in the fruit rather than being converted into cholesterol.
- This innovation offers a plant-based dietary source of Vitamin D, addressing a global health deficiency while providing a sustainable alternative for vegans and those with restricted diets.
