Arbuscular mycorrhizal fungi (AMF) are a diverse group of soil-dwelling fungi that form symbiotic associations with land plants. AMF-plant associations promote the accumulation of plant terpenoids beneficial to human health, although how AMF mediate terpenoid accumulation is not fully understood. A critical assessment and discussion of the literature relating to mechanisms by which AMF influence plant terpenoid accumulation, and whether this symbiosis can be harnessed in horticultural ecosystems was performed. Modification of plant morphology, phosphorus availability and gene transcription involved with terpenoid biosynthetic pathways were identified as key mechanisms associated with terpenoid accumulation in AMF-colonised plants. In order to exploit AMF-plant symbioses in horticultural ecosystems it is important to consider the specificity of the AMF-plant association, the predominant factor affecting terpenoid accumulation, as well as the end use application of the harvested plant material. Future research should focus on resolving the relationship between ecologically matched AMF genotypes and terpenoid accumulation in plants to establish if these associations are effective in promoting mechanisms favourable for plant terpenoid accumulation.
丛枝菌根真菌（AMF）是一类多样的土壤真菌，它们与陆生植物形成共生关系。AMF与植物的共生关系促进了对人体健康有益的植物萜类化合物的积累，尽管AMF如何介导萜类化合物的积累尚未完全了解。本文对与AMF影响植物萜类化合物积累的机制相关的文献进行了批判性评估和讨论，并探讨了这种共生关系是否可应用于园艺生态系统。植物形态的改变、磷的有效性以及与萜类生物合成途径相关的基因转录被确定为与AMF定殖植物中萜类化合物积累相关的关键机制。为了在园艺生态系统中利用AMF与植物的共生关系，重要的是要考虑AMF与植物共生关系的特异性，这是影响萜类化合物积累的主要因素，以及收获的植物材料的最终用途。未来的研究应集中于解决生态匹配的AMF基因型与植物中萜类化合物积累之间的关系，以确定这些共生关系是否有效地促进了有利于植物萜类化合物积累的机制。
