Improving micronutrient accumulation and biofortification has gained significant attention as a means to address human nutritional deficiencies through crop improvement. Metabolic engineering approaches have been successful in enhancing the content of various micronutrients in edible plant tissues. Notable examples include golden rice, engineered to accumulate β-carotene in the grain, and high-iron rice varieties. Strategies involve enhancing uptake mechanisms, improving transport and accumulation in edible tissues, and increasing the synthesis of chelating agents to improve micronutrient bioavailability . These biofortification efforts not only aim to improve crop nutritional quality but also contribute to global health initiatives addressing micronutrient deficiencies.
