Drivers of the composition of active rhizosphere bacterial communities in temperate grasslands

摘要

Distribution of OTUs between phytometer rhizosphere and bulk soil compartments. Numbers of unique and shared OTUs and proportion of shared OTUs. From the shared OTUs, 10,949 did not respond to the rhizosphere environment, while 3285 were enriched in the rhizosphere of one to six plant species. Numbers in parentheses and on the left of the bracket give average contribution (relative abundance) of the respective OTUs to all sequence reads in rhizosphere or bulk soil. Frequency of OTUs per sample for bulk soil only, shared or phytometer rhizosphere only OTUs
