We are grateful to Prof. Peter Wolk (Michigan State University) and Prof. Xudong Xu (Institute of Hydrobiology, Chinese Academy of Sciences) for kindly providing the plasmids with resistance cassette for the use of cyanobacterial gene knockout and the antibody of Anti-NrtA for protein location. This study was financially supported by the National Natural Science Foundation of China (No. 31470171), the Fundamental Research Funds for the Central Universities (CCNU15A02022 and CCNU16KFY03) and Natural Sciences and Engineering Research Council of Canada.

Cyanobacteria are globally important primary producers and abundant in many iron-limited aquatic environments. The ways in which they take up iron are largely unknown, but reduction of Fe3+ is an important step in the process. Here we report a special iron permease in Synechocystis, cFTR1, that is required for Fe3+ uptake following Fe2+ re-oxidation. The expression of cFTR1 is induced by iron starvation, and a mutant lacking the gene is abnormally sensitive to iron starvation. The cFTR1 protein localizes to the plasma membrane and contains the ...
