药用植物与其生境中的微生物关系密切，两者相互影响，相互作用，形成了植物-微生物共生体系统。微生物与药用植物的生长、繁殖和次生代谢活动息息相关，其互利共生关系是近年来药用植物研究的热点。本文概述了药用植物与微生物的互利共生关系，主要包括：药用植物类型及药用植物根系分泌物对微生物群落结构及多样性的影响，根际微生物对药用植物生长发育的影响以及药用植物与微生物分子识别机制。本文为药用植物与微生物互作机制的发掘和利用提供依据，对有效利用微生物促生机制来提高药用植物抗逆性、增加药材产量和改善质量具有重要意义。

Medicinal plants and microorganisms show a close relationship, both of which are from the plantmicroorganismsymbiont system and interact mutually. Microorganisms are closely related to the growth, reproduction andsecondary metabolic activities of medicinal plants. The symbiotic relationship between medicinal plants and microbes isthe hotspot of medicinal plants in recent years. This paper summarized the relationship between medicinal plants andmicroorganisms. It reviewed the effects of medicinal plant species and root exudates on the microbial communitycomposition and diversity, the effects of medicinal plant rhizosphere microbes on plant growth, the specificity ofmicroorganism and the molecular recognition mechanism of medicinal plants and microorganisms. This article alsoprovided the basis for excavation and utilization of the mechanism of interaction between medicinal plants andmicroorganisms, which were significance for the effective use of microbial growth mechanism to improve the stressresistance of medicinal plants, to increase the yield and to improve the quality of medicinal plants.
