Tomatoes genetically edited to produce vitamin D | genetic editing

Have you taken a good look at the two tomatoes that illustrate this article? They look pretty much the same. But there is one big difference: the tomato on the left was genetically edited to produce vitamin D. This was made possible because an international team of scientists edited a gene in the tomato that encodes a protein that normally converts provitamin D3 (a precursor to vitamin D3) into cholesterol, which resulted in the accumulation of this provitamin. Then, through treatments with ultraviolet light, this provitamin was transformed into vitamin D3. The results are presented this Monday in the scientific journal Nature Plants and may have their contributions to public health.
