铁对于植物生长至关重要。同时，Fe 通过芬顿反应具有高反应性和毒性。因此，植物严格控制铁稳态并对铁缺乏和铁过载做出反应。植物对铁可用性的反应能力最终会影响人类的营养，包括作物产量和可食用组织的铁浓度。因此，阐明铁的吸收和运输机制对于培育营养更丰富、对铁含量有限的土壤更耐受的作物至关重要。这篇综述涵盖了植物中铁的运输和稳态，重点关注过去五年发表的研究。由于 Fe 转运蛋白通常具有广泛的底物，因此我们还研究了 Fe 与经常伴随 Fe 吸收的有毒金属（即 Cd、Co 和 Ni）之间的关系。我们首先讨论根部对铁的吸收，然后长距离运输到芽，最后将铁装载到种子中。而且，由于铁对于线粒体和叶绿体的代谢至关重要，因此我们还研究了细胞内水平铁运输和稳态的最新发现。我们不讨论这些运输商的监管，因为这个主题最近已经过审查。 1
Fe is essential for plant growth. At the same time, Fe is highly reactive and toxic via the Fenton reaction. Consequently, plants tightly control Fe homeostasis and react to Fe deficiency as well as Fe overload. The ability of plants to respond to Fe availability ultimately affects human nutrition, both in terms of crop yield and the Fe concentration of edible tissues. Thus, elucidating the mechanisms of Fe uptake and transport is essential for the breeding of crops that are more nutrient rich and more tolerant of Fe-limited soils.This review covers Fe transport and homeostasis in plants, focusing on the research published in the past five years. Because Fe transporters often have a broad range of substrates, we also examine the relationship between Fe and the toxic metals that often accompany Fe uptake, namely, Cd, Co, and Ni. We begin by discussing Fe uptake into the root, then long-distance transport to the shoot, and finally, the loading of Fe into seeds. And, because Fe is essential to the metabolism of the mitochondria and chloroplast, we also look at the recent discoveries in Fe transport and homeostasis at the intracellular level. We do not cover the regulation of these transporters because this topic has been recently reviewed. 1
