Phosphorus (P) and iron (Fe) are two essential mineral nutrients in plant growth. It is widely observed that interactions of P and Fe could influence their availability in soils and affect their homeostasis in plants, which has received significant attention in recent years. This review presents a summary of latest advances in the activation of insoluble Fe-P complexes by soil properties, microorganisms, and plants. Furthermore, we elucidate the physiological and molecular mechanisms underlying how plants adapt to Fe-P interactions. This review also discusses the current limitations and presents potential avenues for promoting sustainable agriculture through the optimization of P and Fe utilization efficiency in crops.
磷（P）和铁（Fe）是植物生长的两种必需矿物质营养元素。人们广泛观察到，P 和 Fe 的相互作用会影响它们在土壤中的有效性，并影响它们在植物中的体内平衡，近年来这一现象受到了极大关注。本综述总结了近年来土壤特性、微生物和植物对不溶性 Fe-P 配合物的激活作用的最新进展。此外，我们还阐明了植物适应 Fe-P 相互作用的生理和分子机制。本综述还讨论了目前的局限性，并提出了通过优化作物中 P 和 Fe 的利用效率来促进可持续农业的潜在途径。
