"Arbuscular mycorrhizal fungi (AMF) are important plant symbionts and can play a crucial role in phytoremediation - the use of green plants to remove, contain or render soil contaminants. Phytoremediation of heavy metals (HM) requires plant species with high biomass and HM uptake abilities. Transgenic plants of fast growing species with ability to acummulate more HM in above-ground tissues can be an effective alternative for the remediation of upper soil horizons. An assessment of the accumulation effectivity for HM will be more realistic, when AMF and their complex role in element cycling in soil will be considered as an integral part of the phytoremediation system. The roles of AMF in phytoremediation can consist in a positive influence on plantsurvival and fitness under adverse conditions in contaminated soils, in the sequestration of HM in mycelium or an alteration of the HM uptake and translocation to shoots. In order to optimalise a phytoremediation system, the capability of transgenic"@en . . . "2"^^ . . . . "Neuvedeno."@en . .
