Rice is one of the most important staple crops and efficient iron (Fe) adsorption during growth not only improves rice yield, but also enriches this essential micronutrient in rice grains to address Fe deficiency in humans. In this article, we review updates on research into the molecular mechanisms regulating Fe uptake from soil and its transport from roots to shoots to seeds in rice plants. Understanding the regulation and expression of genes involved in Fe homeostasis will benefit the development of variants with enhanced Fe utilization to improve rice output and quality.
大米是最重要的主食作物之一，在生长过程中高效地吸收铁（Fe）不仅可以提高水稻产量，还可以增加稻米中铁这一必需微量元素的含量，从而解决人体缺铁问题。本文综述了水稻从土壤中吸收 Fe 及其从根部向地上部和种子运输的分子调控机制的最新研究进展。深入了解 Fe 稳态相关基因的调控和表达，有利于开发利用增强 Fe 吸收利用效率的品种，从而提高水稻的产量和品质。
