高等植物利用各种机制维持铁的动态平衡。为了从根际获取少量的可溶性铁，禾本科植物合成天然的铁(III)螯合剂，称为芥酸家族植物铁素载体(MA)。最近的研究发现了与铁吸收和转运有关的各种基因，以及调节这些基因表达的因素，特别是在水稻中。对这些分子成分的操纵被用来培育对铁缺乏的耐受性增强的转基因作物，或具有高种子铁含量的转基因作物。由于铁的动态平衡与其他矿质元素的动态平衡密切相关，对这一现象的理解将为生产低浓度有毒金属的作物和用于植物修复的转基因植物奠定基础。
Higher plants utilize various mechanisms to maintain iron homeostasis. To acquire sparingly soluble iron from the rhizosphere, graminaceous plants synthesize natural iron (III) chelators known as mugineic acid family phytosiderophores (MAs). Recent research has uncovered various genes involved in iron uptake and translocation, as well as factors regulating the expression of these genes, especially in rice. Manipulation of these molecular components is used to produce transgenic crops with enhanced tolerance to iron deficiency, or with a high seed iron content. Since iron homeostasis is closely linked to that of other mineral elements, an understanding of this phenomenon will serve as the basis for the production of crops with low concentrations of toxic metals and transgenic plants for phytoremediation.
