Insight into bacterial and archaeal community structure of and rhizosphere in response to different salinity level.

play an important ecological role in reclamation and improvement of agricultural saline soil due to strong salt tolerance. At present, research on salt tolerance mainly focuses on the physiological and molecular regulation. However, the important role played by microbial communities in the high-salinity tolerance of is poorly studied. Our findings have important implications for understanding the distribution patterns and the driving mechanisms of different Suaeda species and soil salinity levels. In addition, we explored the key microorganisms that played an important ecological role in rhizosphere. We provide a basis for biological improvement and ecological restoration of salinity-affected areas.
