Figure 5. Dendrogram formed by neighbour joining method, which shows the relationship of Pyrenophora isolates (see Table 2) based on sequence similarities for the ITS1and ITS2 regions. Distance estimation was calculated using an algorithm by Jukes and Cantor (1969). The distance scale represents the evolutionary distance as 0.1 fixed mutations per site. One hundred samples were used for the bootstrap analysis and values above 50 are shown.
