Future Perspectives and Emerging Trends in Crop Biofortification

Crop biofortification, the process of enhancing the nutritional content of crops through genetic or agronomic interventions, has garnered significant attention as a sustainable approach to address global malnutrition. It has been estimated that nearly three billion people are deficient in one or more vitamins/mineral elements making them prone to different diseases such as anemia, beriberi, pellagra, night blindness, rickets, and scurvy. These facts highlight the importance of crop biofortification to increase the nutritional value of food for overcoming the “hidden hunger” problem due to micronutrient deficiency, especially of the vulnerable communities living in poor geographics. Biofortified crops have demonstrated success in addressing these deficiencies, with staple crops such as rice, wheat, maize, pearl millet, finger millet, and beans being targeted for improvement. Advancements made in “omics” technologies including genomics, proteomics, metabolomics, and phenomics, coupled with plant breeding and genetic engineering methods, have provided unprecedented opportunities to develop nutritionally-rich and climate resilient crops. Recent breakthrough in genome editing methods has opened new avenues for increasing the bioavailable concentration of essential elements in crop plants. Rational combination of these new research domains along with conventional breeding and metabolic engineering strategies should enable advancement in developing sustainable, stakeholder acceptable, and cost-effective techniques and methodologies for developing nutrient-enriched staple food option for millions of people globally. Collaborative efforts and continued research are essential to overcome obstacles and ensure the successful integration of biofortified crops into agricultural systems, thereby contributing to improved public health and sustainable development.
