FIG. 1.

Phylogenetic tree based on AFLP fingerprints with all 16 primer pair combinations of MseI +1-EcoRI +1 from MseI- and EcoRI-digested fragments. Bootstrap values are percentages of 1,000 replications and are indicated at the nodes if the value is greater than 50%. Isolates indicated by an asterisk are shown twice, in the position found in the tree as originally derived (solid line) and in the position found when fragments specific to these isolates were omitted (dashed line; see text). The value of the bar represents genetic distance measured by Dice coefficient.
