Fig. 2.

Relative abundance of the 20 most abundant acdS bacterial genera (all Proteobacteria or Actinobacteria) present in bulk soil and common to each rhizophere at 21 days in cropped (a) or meadow (b) soil. The remaining sequences (< 8% in cropped soil and < 6% in meadow soil) are not pictured. Mean values across six replicates are shown for each treatment. The same colors were used in a and b for genera common to both soils
