Golden rice was engineered from normal rice by Potrykus and Beyer in the 1990s. The typical golden colour is due to the production of $\beta$-carotene a precursor of vitamin-A. Golden rice differs from its parental strain by the addition of three $\beta$-carotene genes. These included two genes from daffodil plant and third from a bacterium. The incorporation of these genes allows the rice plant to modify certain metabolic pathways in its cells to produce $\beta$-carotene.

  1. Stem.
  2. Seed.
  3. Leaves.
  4. All of these.
