Abstract:

Soil is an important source and material basis of plant nutrients. In recent years, the incomplete management of three industrial wastes (waste gas, waste water, and waste residue), mining production activities and agricultural fertilizer abuse have caused the enrichment of heavy metal Pb, which is a toxic and harmful heavy metal. The heavy metal Pb is not easily degraded in the soil, leading to Pb pollution, causing Pb enrichment in plants, affecting the growth and development of plants. And eventually, the heavy metal Pb is enriched in human body through the food chain and endangers human life. Currently, microbial remediation technology is an economical and efficient method to manage heavy metal Pb contamination. AMF, as the fungus most closely related to human agricultural production, has been a research hotspot in the scientific community. However, less attention has been paid to research on assisting plants to resist Pb stress. Therefore, this paper mainly reviewed the effects of Pb toxicity on plants, the mechanisms and applications of AMF in improving plants’ resistance to heavy metal Pb stress, expecting to provide basic information for maintaining sustainable agricultural production and ensuring human health, as well as plant adversity physiological research and management of heavy metal Pb stress in plants.

Key words: microbial remediation, AMF, plant, Pb stress
