Figure 5

Nonmetric multidimensional Scaling (NMDS) diagram. The ordination analysis based on the Jukes-Cantor genetic distances among 6 environmental clones and 2 isolates representing sequences of Jenufa minuta detected in Europe on various hard substrates. For the analysis, 18S partial sequences comprising hypervariable regions V2, V3, and V4 were used. The red-colored points represent sequences from the walls of castle Gleichen/Germany, the blue ones are from the bunker on Helgoland, an offshore island in the North Sea. For the corresponding accession numbers of the sequences see Table 1.
