The roles of ectomycorrhizal fungi and bacteria associated with corresponding fungal species in distribution of heavy metals within roots and shoots of inoculated pine (Pinus sylvestris L.) seedlings were determined in this study. The mycorrhizal fungi forming different morphotypes were identified by PCR-RFLP using respective primers for an internal spacer transcribed region (ITS) of fungal rDNA. Amongst five fungal species detected, three were identified as Scleroderma citrinum, Amanita muscaria and Lactarius rufus. These fungi used for inoculation of pine seedlings significantly reduced translocation of Zn(II), Cd(II) or Pb(II) from roots to shoots, and the pattern of metal-accumulation was dependent on the fungal species. Ectomycorrhizae-associated bacteria identified as Pseudomonas were used as an additional component of the pine inoculation. These dual root inoculations resulted in higher accumulation of the metals, especially Zn(II), in the roots compared to the inoculation with fungal species alone. Consequently, dual inoculation of pine seedlings could be a suitable approach for plant protection against heavy metals and successful planting of metal-polluted soils.
