    Question: The Fertilizer Control Order was introduced in: ((MCAER 2014))

    Options:

    Beta-carotene
    Vitamin C
    Iron
    Folic acid

    ✅Explanation: Golden rice is a genetically modified variety of rice that has been engineered to produce beta-carotene, a precursor to vitamin A. This makes it a valuable food source for people in regions with vitamin A deficiency.

    🔑Key Points:
    -Golden rice is a transgenic rice variety.
    -Transgenic plants are obtained through genetic engineering that uses recombinant DNA technology.
    -Transgenic plants are generated by introducing foreign DNA into a cell and regenerating a plant from that cell.
    -Golden rice is rich in vitamin A.
    -It is a genetically modified variety of rice (Oryza sativa).
    -It contains good quantities of β-carotene, the precursor of vitamin A.
    -The rice grains are yellow in colour due to presence of β-carotene, thus it is commonly called golden rice.
    -This strain of rice is developed to deal with the vitamin A deficiency in nutrient deficient population.
    -It is one of the successfully biofortified food.

    🛑Additional Information:
    -Genetically modified plants contain high nutritional value of food.
    -Genetic modification has made crops more tolerant to the abiotic stress, and helped to post harvest losses.
    -Reduced reliance on chemical pesticides and increased efficiency of mineral usage by plants.
    -Example- Flavr savr tomatoes, Bt cotton, etc.
