  1. a To calculate all the indices, the sequences number in each samples were normalized to the same, with 9042 bacterial 16S rRNA gene sequences and 8585 fungal ITS sequences
  2. b Abbreviation of the samples name: stroma (ZiZuo in Pinyin simplified as stromata), membrane covered around larva (JunPi in Pinyin simplified as external mycelial cortices), larva (ChongTi in Pinyin simplified as sclerotia) and the soil adhering to the surface of the membrane covered DCXC.
