In the middle of February 2004, a new breed of genetically modified tomato was cultivated by American scientists. It contains a special kind of anthocyanin-containing substance and displays a strange purple color. It also has the function of preventing cancer and myocardial infarction. The paper published by Oregon State University's Cal Jones and others in the professional journal Genetics said that anthocyanins are a kind of flavonoids that are widely distributed in grapes, blood oranges, purple cabbage, eggplant and cherries. In the plant. Plants containing this substance vary in color depending on the content of anthocyanins contained. Red wine also contains this substance. This substance has some efficacy in preventing heart disease. Scientists say that 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. To make tomatoes "healthier foods healthier," they tried to implant tomatoes with a gene that could control the production of anthocyanins and succeeded. Scientists have confirmed that stably produced anthocyanins in this genetically modified tomato have achieved the intended purpose. Scientists also hope that they can use similar methods to implant tomatoes with genes that can produce other healthy substances, making tomatoes and other healthy foods more and more healthy.
