ABSTRACT

Panax notoginseng is a well-known Chinese herb that is used worldwide. Studies on the factors affecting the quality of Panax notoginseng have mainly focused on the physical and chemical properties of the soil, with little reference to the differences in the microbial structure of different production areas. The goal of this work was to explore the diversity and structure of rhizosphere microbial communities of Panax notoginseng. To do this, Panax notoginseng rhizosphere soil samples were collected from ten production areas in China, and the 16SrRNA and internal transcribed spacer (ITS1) sequences were analyzed by Illumina high-throughput sequencing technology. The results revealed similar species composition of fungal and bacterial communities in the different producing areas, but significant variation in the abundances of some dominant flora. Redundancy analysis showed that environmental factors explained 41.3% of the fungal community and 45.7% of the bacterial community. Among all samples, the beneficial fungus Chaetomium was the most abundant with an average abundance of 19.65%. We detected significant enrichment of some root rot pathogens, including Ilyonectria, Fusarium, and Pseudomonas, in samples from Wenshan City and Yunnan Province. In summary, the results reveal differences in the structure of rhizosphere soil microbial community of Panax notoginseng in different production areas. The results of this study show that there are differences in the structure of rhizosphere soil microbial community of Panax notoginseng in different producing areas and some rhizosphere microbes may be related to rhizosphere rot. The results of this work should be beneficial to the agricultural development of Panax notoginseng and can provide a theoretical basis for the control of diseases and pests during cultivation of this important plant.
