  1. 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 1% of total reads and varying significantly have been presented. For each genus, significant differences are presented by different letters (a b c for the bulk soil comparison; A B C for the rhizosphere comparison; ANOVA, P < 0.05). The asterisks correspond to the range of p value (‘*’ means the p-value < 0.05, ‘**’ means the p-value < 0.01, ‘***’ means the p-value < 0.001).
