Main findings: The Sb resistant bacterium impacted the fraction and quantity of IP on rice roots, and it decreased the Sb concentrations in rice shoots. © 2019 Elsevier LtdIron plaque (IP) is crucial in mitigating antimony (Sb) uptake and accumulation in rice plants, while, few studies focused on the effect of the iron plaque-associated Sb resistant bacteria on IP and Sb uptake into rice plants. Here, the effect of a Sb resistant bacterium (GenBank accession No. MH345840, with potential of conversion soluble Sb(III) into insoluble Sb2O3) on IP...
