ABSTRACT
476Micronutrient deficiency presents a considerable threat to achieve nutritional security globally. The intensity of the challenge becomes evident from the fact that nearly half of the global population is affected severely by micronutrient malnutrition. Among major micronutrient deficiencies, the most prevalent concern is related to iron (Fe), zinc (Zn), and vitamin A. Various scientific strategies have been suggested to address the challenge of micronutrient deficiency, of which developing nutrient dense food crops remains the most attractive in terms of cost-effectiveness, sustainability, and environmental safety. This strategy known as crop biofortification can be implemented using modern biotechnology and plant breeding approaches. The development of genetically engineered “golden rice” enriched with beta carotene illustrates a well-established example of bio-fortification via biotechnological techniques. In a similar way, breeding for nutritionally rich crop genotypes also offers a potential method to facilitate nutritional enhancement. In this article, we provide an overview on the current status of crop biofortification along with future projections toward the expansion of biofortified produce.
