Golden Rice (Oryza sativa) denotes a genetically modified rice capable of biosynthesizing and accumulating β-carotene (provitamin A) in the endosperm, yielding a characteristic yellow color in the polished grains.

Vitamin A deficiency causes mortality and growth retardation in children and frequently impairs vision, leading to blindness. It also contributes indirectly to anemia by interfering with iron bioavailability.
