FIGURE 1.

DGGE analysis 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. Sequenced fragments are marked with progressive numbers. The three lanes labelled as “M” refer to a laboratory-prepared reference marker (detailed in the paragraph “PCR-DGGE Analysis”).
