Future Work

In order to use AMF into remediation technologies on a higher scale, it is still necessary to address different important aspects, such as to:

• Understand the ecology, physiology, and evolution of AMF involved in the sequestration and accumulation of PTEs and the mechanisms involved

• Learn about the biogeochemical processes involved in plant-based remediation of polluted soils

• Elucidate the role of AMF in the rhizosphere of high accumulators and hyperaccumulator plants

• Select tolerant AMF species by screening of different polluted conditions and metals (mines, sewages, and industrial sites

• Conduct more detailed studies regarding mechanisms, including genetic and molecular ones, involved in AM-mediated improvement of plant tolerance to PTE

• Increase the understanding of the extent of inter- and intraspecific variation of AMF

• Select successful plant-fungi combinations for suitable soil recuperation areas

• Compare different behavior of species alone and in consortia of native AMF in polluted soils to understand the function of the AMF species on this

• Conduct genetic and molecular studies regarding PTE tolerance in AMF, in general, because their mechanisms remain mostly unknown
