Arbuscular mycorrhizal fungi (AMF) are a kind of symbiotic endophytic fungi that widely colonize into plant roots, which play important roles in promoting plant growth and enhancing resistance to heavy metals. Cadmium (Cd) is a highly toxic material and can be enriched in plants, causing food chain toxicity. Based on the latest research progress at home and abroad, our summarized and analyzed the effects of AMF on the growth of host plants under Cd stress, the accumulation of active components, as well as the absorption to Cd and its accumulation, distribution, migration and transport. In the paper, the mechanism of AMF in enhancing the resistance of host plants to Cd stress was summarized, and the mechanisms were explained from the physiological and molecular perspectives, and the possible regulatory mechanisms of each pathway were discussed. In addition, taking the system of Panax notoginseng (Burk.) F. H. Chen-AMF-Cd system as an example, the diagram of AMF in enhancing the plant resistance to Cd was drew out. This review has important reference value for studying the mechanism of coordination between AMF and host plants to regulate Cd stress, solving the problem of Cd pollution in soil, implementing ecological agriculture or ecological cultivation of Chinese medicinal herbals, and reducing Cd accumulation in the medicinal and edible parts of plants.
