Rice Biofortification: Approaches to Enhance Grain Iron and Zinc Content | Crop Development Research

Publication: Frontiers in Plant Science Summary: Thirty-seven biofortified rice varieties are available for commercial cultivation, 29 rich in zinc. The Indian Agricultural Research Institute revised the levels of zinc in polished rice to 24 mg/kg (85% of the breeding target). Zinc rice can provide up to 60% of daily zinc needs and help reduce zinc deficiency in countries where rice is a staple such as Bangladesh, Indonesia, Philippines, and India. Tools and opportunities for the development of nutri-dense rice varieties are discussed.

Agronomically Biofortifying Crops to Alleviate Malnutrition | Crop Development Research

Publication: Millets – Rediscover Ancient Grains | Summary: Farmers and crop producers can nutritionally enhance food crops like millets and sorghum by applying nutrients directly on plants during the growing process using micronutrient fertilizers. By improving the nutritional status of crops, it can improve the nutritional status of humans who eat those crops—a proven strategy for combatting micronutrient deficiencies.

Future Directions for Millet Biofortification | Crop Development Research

Publication: Frontiers in Plant Science | Summary: A review of recent genetic and genomic innovations that can be explored to enhance grain micronutrient density in millets, a food key source for people living in dryland tropics and drought-prone areas of South Asia and sub-Saharan Africa.

Yield and Agronomic Performance of Provitamin A Maize: DR Congo | Crop Development Research

Publication: Open Agriculture | Summary: To promote crop improvement and adoption of improved varieties by farmers, maize genotypes were evaluated and recommendations made for high performing varieties that will contribute to improved food and nutritional status in children in the South-East of the DR Congo.

Biofortification to Avoid Malnutrition Amid a Changing Climate | Climate Research

Publication: Frontiers in Plant Science | Summary: Increasing temperatures and CO2 levels affect global crop productivity, resilience, and nutrition. This review explores crop breeding techniques to enhance micronutrient bioavailability in seed, tuber, and storage roots. Nutrient uptakes in plants, the distribution of nutrients in the edible parts of crops, the molecular basis of nutrient transport and absorption in humans, and the achievements of breeding nutrient-dense crops are discussed.

Wheat Biofortification to Alleviate Malnutrition | Nutrition Research

Publication: Frontiers in Nutrition | Summary: An editorial for a special issue on the role of nutrient-enriched wheat in nutritious and sustainable food systems that combat micronutrient deficiencies. The special issue includes an update on recent progress made on biofortification and the latest approaches to increase wheat micronutrient content.
