FIGURE 2.

Dendrogram obtained from Unweighted Pair Group Method Using Arithmetic Average (UPGMA) analysis, using Dice’s coefficient, of DGGE profiles of endophytic bacterial communities associated with durum wheat (cultivars Odisseo, O, and Saragolla, S) roots 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 roots of durum wheat not inoculated. Cophenetic correlation is shown at each branch by numbers and coloured dots, ranging between green-yellow-orange-red, according to decreasing values. Standard deviation is shown at each node by a grey bar.
