Perhaps the best-known example of a GM plant is golden rice. Created through the efforts of Ingo Potrykus, a professor at the Swiss Federal Institute of Technology in Zurich, this crop was genetically modified to contain beta-carotene (or vitamin A). This vitamin improves the rice’s nutritional value and could improve the lives of millions of people for whom this is a primary food. It was Potrykus’s dream that this enriched golden rice (so-called because of its pale yellow color) would feed hungry children all over the world. Since rice does not naturally contain beta-carotene, Potrykus needed to find a way to change the genetic makeup of normal rice. He and his colleagues introduced genes from daffodils and a bacteria into the genetic code of normal rice. They also infected white rice with another bacteria for beta-carotene. This new transgenic rice plant could then be bred with rice that grew well in different climates.
