Fig. 3. Relationship between the proportionality of change (Rho, Y axis) and the nucleotide divergence (mismatches after alignment, X axis).

Only genera with more than 3 ASVs at less than 5 nucleotide divergences were evaluated. Gray and black lines represent the linear relationship between the two variables (black indicates statistical significance). The p value and the R² are displayed for the significant regressions. See Supplementary Table 2 for the correspondence between GTDB and SILVA nomenclature.
