根际是植物-土壤-微生物信息和物质交换的重要场所，是影响植物生长和抗逆性的重要因素。植物根系和根际微生物之间的相互作用对于植物的生长和品质形成至关重要。植物根系通过分泌有机酸、糖类、次生代谢物等物质特异性的促进有益微生物的生长，也能通过自身免疫系统和分泌抗生素抑制病原菌的增殖。根际微生物可以通过多种方式参与药用植物的生长发育、代谢过程以及活性成分的积累，对于药用植物的养分吸收和利用、土传病害防治、非生物胁迫应激等方面具有至关重要的作用。主要对根际微生物对药用植物品质形成的影响及其作用机制的研究进展进行综述，以期为深入了解根际微生物与药用植物间的互作关系提供参考。

The rhizosphere plays important roles in the exchange of information and material among plant-soil-microbes, and is also the major factor effecting on plant growth and stress resistance. The interaction between plant roots and rhizosphere microorganisms is critical for plant growth and quality formation. Plant roots can specifically promote the growth of beneficial microorganisms by secreting organic acids, sugars, and secondary metabolites, etc., and inhibit the proliferation of plant pathogens through its autoimmune systems and the secretion of antibiotics. Rhizosphere microbes can participate in the growth, development, metabolic processes, and active components accumulation of medicinal plants in both direct and indirect ways, and have important contributions on the nutrient absorption, utilization, soil-borne disease control, and abiotic stress responses of medicinal plants. Research progress on effects of rhizosphere microorganisms on quality formation of medicinal plants and their interaction mechanisms are reviewed in this paper, in order to provide reference for further understanding the interaction between rhizosphere microorganisms and medicinal plants.
