Plant rhizocompartments effects on the microbial community structures were calculated using analysis of similarities (ANOSIM) based on the Weighted UniFrac distance metric (999 permutations).
R: root; RS: rhizosphere soil; RZ: root zone soil; Bulk: inter-shrub bulk soil.
Significance levels: P ≤ 0.05; P ≤ 0.01.
