Understanding the Fe deficiency response in plants is necessary for improving both plant health and the human diet, which relies on Fe from plant sources. In this review we focus on the regulation of the two major strategies for iron acquisition in plants, exemplified by the model plants Arabidopsis and rice. Critical to our knowledge of Fe homeostasis in plants is determining how Fe is sensed and how this signal is transmitted and integrated into a response. We will explore the evidence for an Fe sensor in plants and summarize the recent findings on hormones and signaling molecules which contribute to the Fe deficiency response. This article is part of a Special Issue entitled: Cell Biology of Metals.
了解植物对铁缺乏的反应对于改善植物健康和人类饮食（其依赖于植物来源的铁）都很有必要。在本综述中，我们重点关注以模式植物拟南芥和水稻为例的植物获取铁的两种主要策略的调控。对于我们了解植物中铁稳态至关重要的是确定铁是如何被感知的，以及这个信号是如何被传递并整合到反应中的。我们将探讨植物中铁传感器的证据，并总结有关有助于铁缺乏反应的激素和信号分子的最新发现。本文是名为《金属细胞生物学》特刊的一部分。
