Abstract Background and aims Ginsenosides are the main bioactive components of Panax plants which could be secreted by root and show autotoxicity to root cells or promote the growth of soil-borne pathogens. However, comprehensive understanding of the effect of ginsenosides on soil microbiota is still lacking. Methods The ginsenosides in root exudates of P. notoginseng were quantified and exogenous ginsenosides on soil microbiota were tested using 16S rRNA and ITS gene tag sequencing. Then its underlying mechanism was deciphered through studying effects of ginsenosides on growth of the ginsenoside-modified culturable fungi and bacteria as well as the relationships between these fungi and bacteria. Results Exogenous root exudates and mixtures of Rg1 + Rb1 + Rd had similar ability to drive the change of soil Responsible Editor: Birgit Mitter.
