Figure 4

Maximum likelihood (ML) tree of two species of Colemanosphaera and an Austrian strain (ASW05157) based on internal transcriber spacer region of nuclear ribosomal DNA. For details of the methods, see the Methods Section. Branch lengths are proportional to the genetic distances, which are indicated by the scale bar above the tree. Numbers on the left or right side at the branches represent bootstrap values (≥50%, based on 1,000 replicates) obtained with the ML and maximum parsimonious analyses, respectively.
