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 the samples, significant differences [p ≤ 0.05; least significant difference (LSD) test] among the three sampling sites are shown by different lowercase (soil) or uppercase (root) letters within each column.
