Iron is a transient metal essential for the proper growth and development of plants because as a component of the enzymes with a wide redox potential, iron contributes to the key cellular processes. During evolution, plants have developed a wide range of molecular mechanisms for the efficient control of iron homeostasis within their cells, tissues and organs. These include membrane proteins involved in the uptake, long-distance transport and intracellular distribution of iron as well as the iron-storing and iron-chelating proteins, that are involved in the protection of the plant cells from iron excess and/or ensure the proper growth and development of plants under Fe deficiency. Since iron is crucial for the functioning of plants, the proteins involved in the transport, chelation and storage of iron within plant cells are currently thoroughly studied. This work presents the current state of the art in the knowledge of these proteins and their regulatory mechanisms.
铁是一种对植物正常生长和发育必不可少的过渡金属，因为作为具有广泛氧化还原电位的酶的组成成分，铁参与了关键的细胞过程。在进化过程中，植物已经形成了多种分子机制，用于有效控制其细胞、组织和器官内的铁稳态。这些机制包括参与铁吸收、长距离运输和细胞内分布的膜蛋白，以及铁储存和铁螯合蛋白，它们参与保护植物细胞免受铁过量的影响和/或确保植物在缺铁条件下的正常生长和发育。由于铁对植物的功能至关重要，目前正在深入研究植物细胞内参与铁运输、螯合和储存的蛋白质。这项工作展示了这些蛋白质及其调控机制的当前知识水平。
