The role of indigenous and non-indigenous arbuscular mycorrhizal fungi (AMF) on As uptake by Plantago lanceolata L. growing on substrate originating from mine waste rich in As was assessed in a pot experiment. P. lanceolata inoculated with AMF had higher shoot and root biomass and lower concentrations of As in roots than the non-inoculated plants. There were significant differences in As concentration and uptake between different AMF isolates. Inoculation with the indigenous isolate resulted in increased transfer of As from roots to shoots; AMF from non-polluted area apparently restricted plants from absorbing As to the tissue; and plants inoculated with an AMF isolate from Zn–Pb waste showed strong As retainment within the roots. Staining with dithizone indicated that AMF might be actively involved in As accumulation. The mycorrhizal colonization affected also the concentration of Cd and Zn in roots and Pb concentration, both in shoots and roots. ► The role of arbuscular mycorrhizal fungi (AMF) in As uptake was studied. ► Growth of Plantago lanceolata was significantly enhanced by mycorrhizal inoculation. ► Arsenic concentration and uptake significantly depended on the AMF isolate. ► Arbuscular mycorrhizal fungi may be useful for bioremediation of As contaminated wastes. Effect of arbuscular mycorrhizal fungi on As uptake by Plantago lanceolata strongly depends on the origin of fungal isolates.
