Figure 1

Non-metric multidimensional scaling (NMDS) analysis of HhaI-terminal restriction fragment length polymorphisms (T-RFLP) profiles of metagenomic DNA from three soil substrates. T-RFLP profiles of 16S rRNA bacterial (A) and internal transcribed spacer fungal (B) community sequences were obtained from the rhizoplane (circles), rhizosphere (triangles), and non-rhizosphere (squares) of Huana tailings (red symbols), Tambillos tailings (blue symbols) and surrounding soil (black symbols). Each symbol corresponds to a single T-RFLP profile (four samples each site). Stress values for NMDS analysis are shown in each upper right corner.
