Figure 4

Number of core OTUs in the rhizocompartments. The bar graphs represent the relative abundances of core OTUs (orange) in the bacterial (a), archaeal (b), and fungal (c) communities. The Venn diagrams represent the number of core bacterial (d), archaeal (e), and fungal (f) OTUs that were detected from all the samples in the bulk soil, rhizosphere, and endosphere.
