Cellular and whole organism iron homeostasis must be balanced to supply enough iron for metabolism and to avoid excessive, toxic levels. To perform iron uptake from the environment, iron distribution to various organs and tissues, and iron intracellular compartmentalization, various membranes must be crossed by this metal. The uptake and transport of iron under physiological conditions require particular processes such as chelation or reduction because ferric iron has a very low solubility. The molecular actors involved in iron acquisition from the soil have recently been characterized. A few candidates belonging to various gene families are hypothesized to play major roles in iron distribution throughout the plant. All these transport activities are tightly regulated at transcriptional and posttranslational levels, according to the iron status of the plant. These coordinated regulations result from an integration of local and long-distance transduction pathways.

铁转运和信号植入物

必须平衡细胞和整个机体的铁稳态，以提供足够的铁用于新陈代谢，并避免过量的毒性水平。为了从环境中摄取铁，将铁分配到各种器官和组织，以及铁的细胞内区室化，这种金属必须穿过各种膜。在生理条件下铁的吸收和转运需要特殊的过程，例如螯合或还原，因为三价铁的溶解度非常低。最近对从土壤中获取铁所涉及的分子行为者进行了表征。假设属于不同基因家族的一些候选物在整个植物中的铁分布中起主要作用。所有这些转运活动都在转录和翻译后水平受到严格调控，根据植物的铁状况。这些协调的法规源于本地和长距离转导途径的整合。
