Abstract: Codonopsis pilosula (Franch.) Nannf. is a traditional Chinese herbal medicinal plant and a low-cost succedaneum for Panax ginseng and contains various bioactivity components. In this work, we first evaluated the effects of the inoculation of the plant growth-promoting rhizobacteria Bacillus amyloliquefaciens strain GB03 on growth and metabolite accumulation of C. pilosula. The results demonstrated that application of B. amyloliquefaciens GB03 significantly improved the growth ofC. pilosula compared to DH5α, Luria broth medium, and water treatment, respectively. On the other hand, we observed that the content of lobetyolin, one of the most important secondary metabolites in C. pilosula, was obviously improved by inoculation of GB03 and almost reached twice that compared to the other three treatments. In addition, some amino acids of roots were elevated by GB03, although not significantly. In conclusion, B. amyloliquefaciens GB03 could induce positive effects on the growth and further stimulate accumulation of secondary metabolites in C. pilosula.
