As soil cadmium pollution has been more seriously in recent years, the bioremediation of cadmium pollution has received more concerns. Arbuscular mycorrhiza (AM) represents the most widely distributed mutualistic root -fungus symbiosis in terrestrial ecosystems. It's been evidenced that AM can promote plant growth, enhance plant tolerance to heavy metals, influence uptake, transport and accumulation of heavy metals by plants, and thus indicating a huge potential for phytoremediation of heavy metal-polluted soil. The direct and indirect mechanisms underlying remediation of cadmium-polluted soil using AM and the application of AM in phytoremediation
were reviewed and some future research directions in this field were suggested. |
