GM plants have been useful in many ways. Genetic modification has –


• Made crops more tolerant to abiotic stresses like cold, drought, salt, heat, etc.


• Reduced reliance on chemical pesticides (pest-resistant crops)


• Helped to reduce post harvest losses.


• Increased efficiency of mineral usage by plants


• Enhanced nutritional value of food. For example – Vitamin A enriched rice.
