Abstract:

The present study investigated the potential changes in the structure of bacterial communities and their functional profiles in the rhizospheres of Panax notoginseng cultivated under field (CK) and pine forest conditions (T). The rhizospheres of two-year-old P. notoginseng plants were used to extract DNA for metagenomic sequencing and metabolites for metabolomic profiling. The results revealed a higher root weight (p < 0.05) in plants grown under the forest than CK. The rhizospheric bacterial community comprised mainly three dominant phyla including Acidobacteria, Proteobacteria, and Candidatus rokubacteria which accounted for 75% of the total microbial population. Among them, Acidobacteria was the most abundant bacterial taxa, accounting for 42.4% and 40.4% of the total populations in CK and T, respectively. Relative abundances of bacterial genera revealed that Bradyrhizobium, Candidatus koribacter and Edaphobacter, were the dominant genera in both groups. Comparatively, a higher Proteobacteria to Acidobacteria ratio was observed in forest rhizospheres than in field conditions. Candidatus Rokubacteria and Candidatus nitrostelea were identified as biomarker taxa in forest rhizospheres, while the same could be said for taxa belonging to betaproteobacteria and gammaproteobacteria, Burkholderiales and Verrucomicrobia for field rhizospheres. No differential metabolite contents were observed between the two rhizosphere groups, indicating no adverse effects of P. notoginseng cultivation on the soil quality under forest plantation.
