Figure 4

Relative sequence abundance of bacterial phyla associated with different plant compartments [(A) Rhizosphere soil, (B) Root, (C) Stem, (D) Leaf] identified by the three selected primer pairs (799F-1391R, 799F-1193R, and 341F-783Rabc). Proteobacteria OTU has been replaced by 4 OTUs at the subclass level (alpha, beta, gamma, delta). Replicates are displayed in separate bars and also are averaged per primer pair.
