Figure 10From: Microbial iron management mechanisms in extremely acidic environments: comparative genomics evidence for diversity and versatilityDiversity of alternative iron acquisition modules and putative regulatory connections in acidophiles. Light blue: ferrous iron uptake module, Violet: Ferric-dicitrate uptake module, Orange: Ferric-siderophore uptake module, Grey: Metalophosphate/phosphonate uptake module, Orange arrows: Regulatory connections.Back to article page
