This cluster of papers focuses on biofortification, the process of enhancing the nutritional value of staple crops by increasing the content of essential mineral elements such as iron, zinc, and other micronutrients. The papers cover various approaches including agronomic and genetic strategies, as well as the physiological functions, uptake mechanisms, and regulation of mineral elements in plants. The goal is to address micronutrient malnutrition and improve human nutrition through biofortified crops.
