| Research Abstract |
In field investigations, mycorrhizal fungal communities in different mine tailings and heavy-metal contaminated soils in the central south China and effects of mycorrhizal fungal infection on hose-tree growth on the tailings were investigated. As a result, a phylogenetically diverse communities associated with Masson pine and different structures of mycorrhizal fungal communities among different mine sites were found. In laboratory investigations, the heavy-metal tolerances(Cu, Zn, Pb, Ni, Cd) of 50 ectomycorrhizal fungal species were screened and some species which would be available for revegetation in mine tailings and heavy-metal contaminated soils were detected. Furthermore, response mechanisms of ectomycorrhizal fungus-host trees to different heavy-metal stresses were also investigated.
