A greenhouse trial was conducted to investigate the role of arbuscular mycorrhizas (AM) in aiding arsenic (As) uptake and tolerance by Pteris vittata (As hyperaccumulator) and Cynodon dactylon (a multi-metal root accumulator). Plants inoculated with lived and killed native mycorrhizas isolated from an As mine site were grown in a sterile and slightly acidic soil. The infectious percentage of mycorrhizas (0 mg/kg As: 26.4%, 50 mg/kg As: 30.3%, 100 mg/kg As: 40.6%) and the average biomass of shoots in infected P. vittata increased (0 mg/kg As: 2.45 g/pot, 50 mg/kg As: 2.48 g/pot, 100 mg/kg As: 10.9 g/pot) according to the increase of As levels when compared to control. The indigenous mycorrhizas enhanced As accumulation (0 mg/kg As: 3.70 mg/kg, 50 mg/kg As: 58.3 mg/kg; 100 mg/kg As: 88.1 mg/kg) in the As mine populations of P. vittata and also sustained its growth by aiding P absorption. For C. dactylon, As was mainly accumulated in mycorrhizal roots and translocation to shoots was inhibited.
