Abstract:Heavy metal pollution has become a major difficulty in soil environmental problems due to its refractory degradation and accumulation. Mycorrhizal fungi are able to form a reciprocal symbiotic relationship with the host plant, thereby improving the heavy metal resistance of the plant, which conducive to accelerating the vegetation cover of contaminated land, and can hold heavy metals to achieve the reuse of contaminated soil. The detoxification mechanism of heavy metals in host plants by fungi mainly includes structural fixation, nutrient dilution, gene regulation, chelation and auxiliary chelation, and antioxidant. In order to systematically understand the effects of different mycorrhizal fungi (endomycorrhizae and ectomycorrhizae) on hosts under heavy metal stress, the effect and mechanism of mycorrhizal fungi in enhancing the resistance of host plants to heavy metals were reviewed in this article, and future research directions were discussed. This review provides a theoretical reference for the application of mycorrhizal fungi in the remediation of heavy metal-contaminated soil.
