Explanation:
Detailed explanation-1: -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. It is intended to produce a fortified food to be grown and consumed in areas with a shortage of dietary vitamin A.
Detailed explanation-2: -The genetic modification was made by the addition of two genes, phytoene synthase (Zmpsy1) from Zea mays and carotene desaturase (crtI) gene from the common soil bacterium, Pantoea ananatis (syn. Erwinia uredovora) into a temperate japonica rice variety, Kaybonnet, from the USA.
