Diverse Bacterial Communities From Qaidam Basin of the Qinghai-Tibet Plateau: Insights Into Variations in Bacterial Diversity Across Different Regions.

ABSTRACT: The Qaidam Basin of the Qinghai-Tibet Plateau is a cold, hyper-arid desert that presents extreme challenges to microbial communities. As little is known about variations between surface and subsurface microbial communities, high-throughput DNA sequencing was used in this study to profile bacterial communities of the soil samples collected at different depths in three regions in the Qaidam Basin. The α-diversity indices (Chao, Shannon, and Simpson) indicated that bacterial abundance and diversity were higher in the east and the high-elevation regions compared to the west region. In general, Firmicutes was dominant in the west region, while Proteobacteria and Acidobacteria were dominant in the east and the high-elevation regions. The structure of the bacterial communitie
