All the data presented correspond to the mean relative abundance (±Standard Error of the Mean) of four independent replicates collected along the toposequence of Montiers. Only the genera accounting for more than 0.25% of total reads and that were significantly increased in beech rhizosphere have been presented. For each genus, the significant differences are indicated with asterisks (‘*’ means the p-value < 0.05, ‘**’ means the p-value < 0.01, ‘***’ means the p-value < 0.001).
