摘要/Abstract

摘要： 萜类化合物在植物生长及适应环境变化过程中发挥着重要作用,是某些药用植物的主要活性成分。丛枝菌根（AM）真菌是一类能够与大多数陆地植物形成共生关系的土壤真菌,其在促进植物生长及调节植物次生代谢方面具有重要作用,因而对于提高植物,尤其是药用植物萜类活性成分含量具有潜在应用价值。收集整理了2000年-2019年期间发表的相关文献,提取了宿主植物种类、萜类化合物种类、萜类化合物积累部位、AM真菌种类、试验条件及试验处理类型等数据,综合分析了AM真菌影响植物萜类化合物合成与积累的研究进展。从AM真菌调节萜类化合物合成的营养和非营养机制,以及转运和积累等方面阐述了AM真菌影响萜类化合物含量及其机制,并讨论了试验条件、接种方式及环境因子对AM真菌调节植物萜类化合物合成与积累的影响,分析了当前研究不足,并对未来的研究方向作出展望。

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
