Golden rice is a variety of rice ( Oryza sativa) produced through genetic engineering to biosynthesize beta-carotene, a precursor of vitamin A, in the edible parts of the rice.
May 28, 2024 · Golden rice, a genetically modified rice (Oryza sativa) that has been engineered to biosynthesize beta-carotene, a precursor to Vitamin A. Beta-carotene, a pigment responsible for the orange coloration of carrots and other plants, gives the rice its distinctive hue.

May 28, 2024 · Golden rice, so named because of its rich yellow colour, was genetically engineered to contain higher levels of the micronutrients iron and zinc in the grains while also producing beta-carotene, a precursor to vitamin A. In 2021, the Philippines became the first country to approve commercial production of the rice variety.
May 23, 2019 · Golden Rice is a new type of rice that contains beta-carotene (provitamin A), which is converted into vitamin A as needed by the body and gives the grain its golden color. It is developed through genetic engineering and produces two new enzymes that complete the beta-carotene expression in the rice grain.
Golden Rice is intended to be used in combination with existing approaches to overcome VAD, including eating foods that are naturally high in vitamin A or beta-carotene, eating foods fortified with vitamin A, taking vitamin A supplements, and optimal breastfeeding practices.
Golden Rice is a new type of rice that contains beta carotene (provitamin A, a plant pigment that the body converts into vitamin A as needed). This compound is what gives this grain its yellow-orange or golden color, hence its name. Golden Rice is developed through genetic engineering.
The Science of Golden Rice. Rewiring the grain. Metabolic engineering. Golden Rice technology is based on the simple principle that rice plants possess the whole machinery to synthesise β-carotene, and while this machinery is fully active in leaves, parts of it are turned off in the grain.
In doing so, Greenpeace’s brings the whole environmental movement into disrepute, having blocked a multi-year, international, publicly-funded effort to save the lives and the eyesight of millions of children in some of the world’s poorest countries where rice is the main staple.
Sep 17, 2013 · Golden Rice was engineered from normal rice by Ingo Potrykus and Peter Beyer in the 1990s to help improve human health. Golden Rice has an engineered multi-gene biochemical pathway in its genome. This pathway produces beta-carotene, a molecule that becomes vitamin A when metabolized by humans.
