Phytoremediation as a means of cleaning up polluted soils has gained popularity during the last decade due to its convenience and low costs of installation and maintenance. When the target pollutant is biodegradable, this technology exploits the stimulating effect that roots have on microbial processes and physical/chemical modifications in the rhizosphere. Among the microorganisms that affect rhizosphere processes, symbiotic fungi forming mycorrhizas induce a series of changes in plant physiology, nutrient availability and microbial composition
that may determine the outcome of a phytoremediation attempt. Beyond the rhizosphere, mycorrhizal hyphae act as the roots of the roots, and
may thus extend the rhizosphere into the bulk soil by creating a new interface of soil-plant interactions: the hyphosphere. We here discuss some
of the recent results on phytoremediation of organic pollutants with emphasis on processes in the mycorrhizosphere, and highlight future
research priorities. |
