Solution
Golden rice:
- Golden rice is a GMO (genetically modified organism) produced by genetic engineering with the purpose to synthesize beta-carotene, which is not normally present in rice.
- It is a biofortified crop.
- Beta-carotene is a molecule that is converted into vitamin A in the body.
- The golden color of golden rice is due to the accumulation of provitamin A (beta-carotene) and xanthophylls in the endosperm of golden rice, which is yellow in color.
- The result of both carotenoid biosynthesis transgenes made use in golden rice, CRTI (bacterial carotene desaturase) and PSY (phytoene synthase) is lycopene, which imparts a red color.
