High-throughput sequencing reveals soil bacterial community structure and their interactions with environmental factors of the grassland fairy ring.

Fairy rings (FRs) are common ecological grassland landscapes that have been studied for a long time. However, little is known about their interactions with soil physicochemical properties and bacterial communities. This study performed high-throughput sequencing of the 16S rRNA V3-V4 variable regions of soil bacteria in the three concentric zones of chosen FR, namely, the ON zone, on the ring; IN zone, inside the ring; and OUT zone, outside the ring.
