A Mean relative abundance of each bacterial family in the rhizosphere of plants incubated with ¹²CO₂ or ¹³CO₂. N = 3 replicate plants per treatment. Bars represent ± standard errors of the mean. B The results of differential abundance analysis for bacterial families in the rhizosphere; points show the log2 fold change of different bacterial families between the ¹²CO₂ heavy and the ¹³CO₂ heavy fraction (blue) or between the ¹³CO₂ light and the ¹³CO₂ heavy fraction (green) (N = 3). Log2-fold change standard errors of triplicate plants is shown. *** represents taxa with a significant log2fold change (p < 0.001) For the full statistical output see Supplementary Table 5
