  1. Significance with P < 0.05 is indicated in bold (ns, not significant)
  2. RG V. vinifera cv. Red Globe, SY V. amurensis cv. Shuangyou, YL young leaves, ML mature leaves
  3. aAnalysis of similarity (ANOSIM) indicates the degree of difference between groups, where R value closer to 1 indicates that no members are shared, and R value closer to 0 indicates that communities are identical
  4. bMultiple response permutation procedure (MRPP) returns a delta value representative of the observed versus permuted within-group distances
