Golden rice - Wikipedia
Golden rice was created by transforming rice with two beta-carotene biosynthesis genes: psy (phytoene synthase) from daffodil (Narcissus pseudonarcissus) crtI (phytoene desaturase) from the soil bacterium Erwinia uredovora
Golden rice | Description, GMO, Genetic Engineering, Controversy ...
2024年10月17日 · 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.
The science behind Golden Rice
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. By adding only two genes, a plant phytoene synthase (psy) and a bacterial phytoene desaturase (crt I), the pathway is turned ...

2013年9月17日 · 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.
Development and characterization of GR2E Golden rice …
2021年1月28日 · Among the six second-generation Golden Rice (GR2) events received by the International Rice Research Institute (IRRI), event GR2E was found to contain a single intact copy of the inserted DNA...
Golden rice - Nature Biotechnology
In a major technical accomplishment, a team of researchers has inserted three genes into rice to allow the plant to produce beta carotene, the precursor required for animals to make vitamin A.
Golden Rice: Introducing the β-Carotene Biosynthesis Pathway into Rice …
To obtain a functioning provitamin A (β-carotene) biosynthetic pathway in rice endosperm, we introduced in a single, combined transformation effort the cDNA coding for phytoene synthase (psy) and lycopene β-cyclase (β- lcy) both from Narcissus pseudonarcissus and both under the control of the endosperm-specific glutelin promoter together with a ...
Improving the nutritional value of Golden Rice through increased …
2005年4月1日 · 'Golden Rice' is a variety of rice engineered to produce β-carotene (pro-vitamin A) to help combat vitamin A deficiency1, and it has been predicted that its contribution to alleviating...
Golden Rice: Genetic Engineering, Promises, Present Status
2020年7月30日 · Golden Rice is a generic name of genetically modified rice which produces provitamin A (b-carotene) within the endosperm. The name is taken from the yellowish colour of the rice which is visible after it is milled and polished, a routine procedure done to get rid of the outer layers of the grain.
Golden Rice: Introducing the β-Carotene Biosynthesis Pathway into Rice …
2002年4月1日 · It is a variety of rice (Oryza sativa) produced through genetic engineering to biosynthesize betacarotene, a precursor of vitamin A, in the edible parts of rice. Beta-carotene gives golden...
