Study on the effect mechanism of Arbuscular Mycorrhiza on the absorption of heavy metal elements in soil by plants

Abstract

Abstract In recent years, human activities have produced lots of wastes, including a large number of heavy metals, which have entered the natural ecosystem, changing the activity and function of soil microorganisms. AM fungi can adapt to or resist metal stress, which means it has great utilization potentiality in promoting plant growth, enhancing nutrient acquisition and for phytoremediation in heavy metal contaminated soil. On the basis of previous research results, the leading mechanism of metal tolerance of AM fungi, the influencing factors of mycorrhizal effect and the application in promoting the process of phytoremediation are discussed in this paper, which provides theoretical basises for improving plant tolerance and enhancing mycorrhizal strengthening effect under heavy metal pollution.
