Abstract
Iron (Fe), crucial for plant growth, is abundant but poorly available. Plants use specialized mechanisms for Fe uptake, and beneficial microbes enhance this process. This study used *Azospirillum brasilense* mutants (HM053, FP10, *ipdC*) with varying nitrogen fixation and auxin production to investigate Fe uptake in *Zea mays*. Radioactive iron-59 and ICP-MS revealed differences in Fe uptake correlated with mutant function. Radioactive carbon-11 showed altered host carbon resource use, with HM053 significantly increasing root Fe uptake by enhancing <sup>11</sup>C-acidic substrate exudation for Fe-chelation and increasing <sup>11</sup>C partitioning into citrate, nicotianamine, and histidine for Fe translocation.
