Purple Tomato Extended Lives of Cancer-Prone Mice - washingtonpost.com:
"Tomatoes genetically modified to be rich in antioxidants called anthocyanins appeared to extend the life spans of cancer-prone mice, a European study finds.
The modified tomatoes were created by adding two genes (Delila and Rosea1) from the snapdragon flower. The anthocyanins, which belong to the flavonoid class of antioxidants, gave the tomatoes a peculiar purple color.
'The two genes we have isolated are responsible for flower pigmentation and, when introduced in other plants, turned out to be the perfect combination to produce anthocyanins, the same phytochemical found in blueberries,' study author Eugenio Butelli, of the FLORA project, said in a news release."
