光合生物对外界环境的变化作出反应，包括对光色、光强和养分可用性变化的反应。铁是对光合生物功能至关重要的营养物质之一，主要是由于光合光系统、质体和线粒体的电子传递链以及铁在许多关键蛋白质中的结构和功能作用对铁的高需求。考虑到铁需求与光依赖性过程（如光合作用）之间的联系，以及光与铁之间的相互作用，需要对光和铁适应反应进行微调共调节，以优化光合作用并最大限度地减少铁与光之间潜在的危险相互作用。这种调节对于平衡光和营养的可用性在协调光依赖方面的有机体健身是至关重要的。为了实现这种调节，在光信号传导和铁适应控制中存在分子串扰和/或共同效应物。我们探索已知的范例，光铁的相互作用和相关的调节光合生物的健身中心。
Photosynthetic organisms respond to changes in the external environment, including responses to changes in light color, light intensity and nutrient availability. Iron is one of the nutrients that is critical for the function of photosynthetic organisms, primarily due to the high demand for iron in the photosynthetic photosystems, electron transport chains of plastids and mitochondria, and the structural and functional roles for iron in many critical proteins. Given the connection between iron demands and light-dependent processes such as photosynthesis, as well as the interplay between light and iron, there is a need for finely tuned co-regulation of light and iron acclimation responses to optimize photosynthesis and minimize potential dangerous interactions between iron and light. Such regulation is critical for balancing light and nutrient availability in the coordination of light-dependent aspects of organismal fitness. To accomplish this regulation, there is molecular crosstalk and/or common effectors in light signaling and iron acclimation control. We explore known paradigms that are central to light–iron interactions and the associated regulation of fitness in photosynthetic organisms.
