The relative percentages of different assembly processes of microbial communities in tobacco soil based on infer community assembly mechanisms by phylogenetic-bin (iCAMP) measurement over geographic distances for a bacterial, b fungal, and c protistan communities. Different colors represent different assembly processes. Equation for the linear relationships is presented in the plot with the corresponding P-values, which were corrected for nonindependence of pairwise comparisons using a permutation test. Solid lines indicate the mean fits, and the shading represents 95% confidence intervals
