 note = {Miscanthus sinensis Andersson grows naturally at the Hitachi mine. The root‐zone soil was acidic and contained high concentrations of Cu, Pb, Zn and exchangeable Al. Adventitious roots accumulated high concentrations of Al and Fe, but not other heavy metals. The purpose of this study was to elucidate the mechanism of tolerance of Al in M. sinensis, focusing on its chemical interaction with root endophytes. We isolated Chaetomium cupreum, which produced siderophores, from adventitious roots of M. sinensis via CAS assay. In inoculation tests, C. cupreum promoted M. sinensis seedling growth and increased Al and Fe uptake in the roots, although C. cupreum did not stimulate M. sinensis to produce Al detoxicants, such as citric and malic acids. Observation of the pattern of Al localization in the roots clarified that C. cupreum reduced Al toxicity in M. sinensis via compartmentalizing Al into fungal mycelia surrounding the roots and creating a less toxic Al‐localization pattern, allocating Al to the epidermis, endodermis and stele of roots. In conclusion, our results indicated that C. cupreum increases Al tolerance in M. sinensis growing at the acidic mine site.},
