PLANT BIOLOGY: The Green Revolution Strikes Gold

Access to the article is free, however registration and sign-in are required. As Guerinot explains in a Perspective, half of the world's population consume rice as a staple food, yet rice is devoid of many essential nutrients such as vitamin A and iron. Now Ye et al. report that they have successfully engineered rice plants to produce b-carotene (from which vitamin A is made) in the endosperm of the rice grain. As soon as true-breeding lines of this engineered rice are established, seeds will be freely available to farmers in developing countries. This should help to ameliorate vitamin A deficiency, which is widespread in poor parts of the world.
