摘要: Iron (Fe) is an intriguing nutrient due to its dual nature. Its redox properties make it essential for different vital processes in plant cells. But excess of Fe can be toxic as catalyses the formation reactive oxygen species. Therefore homeostasis must tightly regulated. Different mechanisms contribute regulation, including control uptake, intracellular chelation by molecules and partitioning into organelles storage locations. Despite high abundance soil, solubility extremely low. availability represents a significant constraint growth plants have developed distinct strategies ensure solubilisation uptake. The Fe-S clusters electron transport chain mitochondria chloroplasts represent important sink Fe. Recent observations suggest that co-regulation exists between sulfur metabolism. This most likely outcome demand S required biosynthesis clusters. In following chapter uptake their regulation will introduced. Moreover, aspects cell presented, organelles. last section evidences towards interaction metabolism discussed.
