FIGURE 8.

Permutation analysis summarising the relative abundance of the bacterial OTU found in roots of durum wheat (cultivars Odisseo, O, and Saragolla, S) inoculated with either Lactobacillus plantarum (O-B, S-B), or Funneliformis mosseae (O-M, S-M), or L. plantarum and F. mossae (O-BM, S-BM). Controls (O, S) refer to plants of durum wheat not inoculated. Euclidean distance and Mc-Quitty’s criterion were used for clustering. Colours correspond to normalised mean data levels from low (green) to high (red).
