Abstract: Terpenoids play critical role in plants growth and coping with environmental stresses,and are the major active components in medicinal plants. Arbuscular mycorrhizal(AM)fungi are a group of soil-dwelling fungi that may form symbiotic associations with most terrestrial plants. AM symbiosis can improve plant growth and regulate plant secondary metabolisms,therefore AM inoculation is a promising strategy for promoting terpenoid-active ingredient accumulations in medicinal plants. In this paper,current research progresses in AM fungi and plant terpenoid metabolism was reviewed by analyzing the relevant literature published from 2000 to 2019. Factors influencing mycorrhizal effects on plant terpenoid metabolism,such as host plant families,terpenoid species,terpenoid accumulation organs,AM fungal species,experimental conditions,and experimental treatment types,were summarized. Moreover,we discussed the nutritional and non-nutritional mechanisms of mycorrhizal effects on plant terpenoids synthesis,transport and accumulation,which can be influenced by cultivation systems,inoculation methods,and environmental factors. Finally,we proposed the deficiencies and research perspectives in the research field.

Key words: arbuscular mycorrhizal fungi, terpenoids, secondary metabolism, inoculation, non-nutritional mechanisms
