Maintaining the appropriate balance of iron between deficiency and toxicity requires fine-tuned control of systems for iron uptake and storage. Both among fungal species and within a single species, different systems for acquisition, storage, and regulation of iron are present. Here we discuss the most recent findings on the mechanisms involved in maintaining iron homeostasis with a focus on siderophores, low-molecular-mass iron chelators, employed for iron uptake and storage. Recently siderophores have been found to be crucial for pathogenicity of animal, as well as plant-pathogenic fungi and for maintenance of plant-fungal symbioses.

铁载体在真菌生理和毒力中。

要在铁的缺乏和毒性之间保持适当的平衡，就需要对铁的吸收和存储系统进行微调的控制。在真菌物种之间和在单个物种内，都存在用于铁的获取，存储和调节的不同系统。在这里，我们讨论有关维持铁稳态的机制的最新发现，重点是用于铁吸收和储存的铁载体，低分子量铁螯合剂。最近发现铁载体对于动物，植物致病真菌和植物-真菌共生酶的致病性至关重要。
