No Sun, No Problem: CRISPR’d Tomatoes Produce Vitamin D

“We’ve shown that you can biofortify tomatoes with provitamin D3 using gene editing, which means tomatoes could be developed as a plant-based, sustainable source of vitamin D3,” ...

Tomatoes naturally contain provitamin D3 in their leaves at very low levels. Researchers used CRISPR-Cas9 gene editing to turn off the Sl7-DR2 enzyme, which normally converts 7-DHC. This edit resulted in an increase in the levels of 7-DHC in the tomato plants, which was then converted to vitamin D3 through exposure to UVB light.
