Abstract: Medicinal plants are the most important sources of Chinese traditional medicine system,and are the natural treasure for preventing and treating diseases. Rhizosphere is the main location where exchanging the substance and energy between plant and environment happens. Plant growth promoting rhizobacteria can change physicochemical properties of rhizosphere soils in medicinal plants,accelerate transformation of available nutrient and produce corresponding specific substances,subsequently affecting its growth,development,metabolic activities,and so on. These bacteria play an extremely important role in plant growth. We here summarize the recent domestic and overseas research progress on nitrogen fixation,phosphate solubilization,producing hormone and biological control of plant growth promoting rhizobacteria in medicinal plants. We aim to provide a theoretical basis for medicinal plants research and new ideas for the cultivation,production and germplasm innovation of medicinal plants.

Key words: medicinal plants, plant growth promoting rhizobacteria, promoting mechanism
