FIGURE 3.

Relative abundance of dominant bacterial taxa (>1% of total sequences) in different soil and root samples. (A) Nine phyla and (B) 11 genera. NDS, MDS, and HDS represent the soil samples from the non-diseased, moderately diseased, and highly diseased sites, respectively. NDR, MDR, and HDR represent the plant root samples from the non-diseased, moderately diseased, and highly diseased sites, respectively. Data are expressed as mean ± SD (n = 3). For each type of samples, different lowercase (soil) or uppercase (root) letters within each group indicate significant differences among the three sampling sites [p ≤ 0.05; least significant difference (LSD) test].
