Golden rice is a variety of Oryza sativa rice produced through genetic engineering to biosynthesize beta‐carotene, a precursor of pro‐vitamin A in the edible parts of rice. Golden rice was developed as a fortified food to be grown in areas where there is a shortage of dietary vitamin A. Golden
rice was created by transforming rice with three beta‐carotene biosynthesis genes: psy (phytoene synthase) and lyc (lycopene cyclase) gene from daffodil (Narcissus pseudonarcissus) and $crt I$ (Carotene desaturase) from the soil bacterium Erwinia uredovora
