Genetically Modified Plants (GMOs) are the plants, whose genes have been altered by manipulation. Genetic modification of plants is useful in different areas because of following reasons-
(a)  It increases tolerance against abiotic stresses (cold, drought, salt, heat).
(b)  It reduces reliance on chemical pesticides (pest-resistant crops).
(c)  It reduces post-harvest losses.
(d)  It increases the efficiency of minerals used by plants (this prevents early exhaustion of fertility of soil).
(e)  It enhances nutritional value of food, e.g., vitamin-A enriched rice (golden rice).
(f)   It creates tailor-made plants to supply alternative resources such as starch fuels and pharmaceuticals to industries.
