Using transgenic technology to bred purple tomatoes
Scientists in the United States have recently cultivated a new type of genetically modified tomato that appears purple due to the inclusion of an anthocyanin-containing substance and also has the effect of preventing cancer and myocardial infarction. It is understood that anthocyanins are flavonoids that have the effect of preventing heart disease. Some plants, such as grapes, purple cabbage, and eggplant, contain such substances in different amounts and colors. Although tomatoes contain a variety of substances that are beneficial to human health, such as lycopene with certain anti-cancer effects, they do not contain anthocyanins. After years of hard work, scientists in the United States have tried to implant tomatoes with genes that can control the production of anthocyanins and have succeeded.
