Abstract:
The study of spatial patterns in soil microbial communities in mountain ecosystems has received much attention. However, elevational and seasonal patterns and environmental drivers of bacterial communities associated with the plant rhizosphere remain understudied. In this work, we collected 72 soil samples from a subalpine dark coniferous forest at four elevations on Gongga Mountain in May, August, and October 2017. We then studied the distribution patterns and drivers of soil bacterial community composition and diversity using MiSeq sequencing. The results indicated that bacteria in the genera Variibacter (5%), Acidothermus (4.2%), Afipia (2.5%), Bryobacter (2.5%), Acidibacter (1.6%), Isosphaera (1.5%), Rhizomicrobium (1.2%), and Granulicella (0.02%), as well as the species Candidatus Soilbacter (0.05%), were dominant in both the Abies fabri rhizosphere and bulk soil. Bacterial a diversity in both types of soil increased from 2 800 m to 3 200 m and decreased from 3 200 m to 3 500 m. There was a significant correlation between the α diversity of bacterial community and soil pH (r = 0.81, P = 0.001). In addition, there was no significant difference in the structure of the bacterial community in the rhizosphere and bulk soil. Overall, our findings revealed the spatiotemporal dynamics of bacteria associated with plant root in subalpine forest soils and may provide data-based support for a comprehensive understanding of microbial distribution in this ecosystem.
