Table 1. Summary of data and alpha-diversity of the fungal community of rhizospheric soil, plant endophytic and fallow soil samples.
Each plant and soil samples (18 samples) were randomly divided into three subsamples (18 × 3), and were analyzed using the average data of their subsamples, respectively. Different letters in one column denote significant differences at P < 0.01 among the samples from same source. One-year fallow soil (FS_1), 2-year fallow soil (FS_2), 1-year healthy rhizosphere soil (RS_H1), 2-year healthy rhizospheric soil (RS_H2), 2-year root-rot diseased rhizospheric soil (RS_D), blank control soil (no A. macrocephala was planted) (S_CK), 1-year-old healthy root/stem/leaf/tuber (R/S/L/T_H1), 2-year-old healthy root/stem/leaf/tuber (R/S/L/T_H2), 2-year-old root-rot diseased root/stem/leaf/tuber (R/S/L/T_D).
