    Study Notes

    Agricultural Applications of GMOs

    • Genetic engineering boosts crop yields, lowers food production costs, and reduces pesticide use.
    • Enhanced nutrient content and quality, pest resistance, and increased food security are other benefits.
    • Crops are engineered to mature faster and tolerate various stressors (e.g., aluminum, boron, salt, drought, frost).
    • GMOs can produce non-protein products like bioplastics, and non-industrial ones like ornamental plants.
    • Animals are engineered for higher yields and disease resistance (e.g., faster-growing salmon, cattle resistant to mad cow disease).

    Pharmaceutical Applications of GMOs

    • GMOs are used in the pharmaceutical industry.
    • The first plant-produced protein pharmaceutical, human growth hormone, was developed in 1986.
    • The first plant-produced antibody was created in 1989.
    • Tobacco is the primary plant used for expressing foreign genes in this industry, due to intensive research.
    • Plant-produced antibodies are undergoing clinical trials.
    • Transgenic animals are crucial in medical research, carrying human genes or mutated genes to study disease progression and genetic factors.
