Abstract excerpt
The genetic structure of the root-endophyte Phialocephala fortinii was analyzed in three study sites using 11 single-copy RFLP probes. A total of 541 strains isolated from surface-sterilized, fine roots (diameter 0.5-3 mm) of Norway spruce (Picea abies) were examined. The average gene diversity (H) was high in all three study sites. Cluster analysis showed that up to four well-separated clusters of multi-locus...
