Mycorrhizal fungi represent an interface between plants and soil, as they mediate the uptake and transfer of elements from the soil particles to the roots of mycorrhizal plants. For these reasons, there has been increasing interest for these symbiotic fungi in different sectors of agro-environmental biotechnologies. In fact, acting as biofertilisers and phytostimulators, symbiotic fungi allow a natural management of agriculture and more respect for the environment. These symbiotic fungi can also protect their host plants from the toxic effects of heavy metals, thus allowing revegetation of contaminated sites. Despite the documented protection effects, the bio-molecular mechanisms regulating the interaction between heavy metals and mycorrhizal fungi are still largely unknown. They will be discussed in this review, because their understanding is a prerequisite for a better use of these soil biotic components as tools in bioremediation.
