[Health Channel/Comprehensive Report]Vitamin D is an essential trace element for the human body. However, due to economic changes and changes in life, most people have insufficient intake of vitamin D. According to “CNN“Researchers used CRISPR-Cas9 gene editing technology to keep vitamin D in tomatoes, which could help 1 billion people around the world if successful.

Study co-author Cathie Martin, a professor at the John Inness Centre in the UK, said that although vitamin D supplements are available in many countries, if they are consumed in other forms, it means that additional vitamin C can be obtained from tomatoes. Because neither vegetables nor fruits, people are not getting enough. Research published innatural plants》。

For most people, the source of vitamin D in addition to diet is ultraviolet B light (UVB), which is why vitamin D is also called the sunshine vitamin. Researchers have found that the compound in the skin that can make vitamin D is 7- DHC, or vitamin D3, is also found in the leaves and unripe green fruits of tomato plants. The researchers blocked a gene in the tomato plant that normally converts vitamin D3 to cholesterol, allowing vitamin D3 to be present in the ripe tomato fruit.

The study co-author Jie Li, a postdoctoral researcher at the John Innes Center, said that the gene-edited tomatoes looked the same as normal tomatoes and tasted the same. The gene editing did not affect the growth, development and yield of the tomatoes. Separately, the scientist who devised the CRISPR-Cas9 gene-editing technology has won the 2020 Nobel Prize.
