Golden rice is a genetically engineered variety of rice that produces beta-carotene, a precursor to vitamin A, in the edible parts of the rice grain. It was developed to help address vitamin A deficiency in parts of the world where rice is a staple crop. The goals are to provide a sustainable source of vitamin A through a staple food that is accessible and can be grown locally by farmers to consume and sell. The rice was engineered by introducing two new genes that activate the biosynthetic pathway to produce beta-carotene in the endosperm of the rice grain.
