Iron and zinc are critical micronutrients for human health. Approximately two billion people suffer from iron and zinc deficiencies worldwide, most of whom rely on rice (Oryza sativa) and wheat (Triticum aestivum) as staple foods. Therefore, biofortifying rice and wheat with iron and zinc is an important and economical approach to ameliorate these nutritional deficiencies. In this review, we provide a brief introduction to iron and zinc uptake, translocation, storage, and signaling pathways in rice and wheat. We then discuss current progress in efforts to biofortify rice and wheat with iron and zinc. Finally, we provide future perspectives for the biofortification of rice and wheat with iron and zinc.
铁和锌是人类健康的关键微量营养素。全球约有 20 亿人患有铁和锌缺乏症，其中大多数人以水稻（Oryza sativa）和小麦（Triticum aestivum）为主食。因此，通过生物强化来增加水稻和小麦中的铁和锌含量是改善这些营养缺乏的重要且经济的方法。在这篇综述中，我们简要介绍了铁和锌在水稻和小麦中的吸收、转运、储存和信号转导途径。然后，我们讨论了目前在通过生物强化来增加水稻和小麦中铁和锌含量方面的进展。最后，我们对水稻和小麦中铁和锌的生物强化提供了未来的展望。
