Neighbor joining tree from ISSR fingerprints of A. terreus isolates. Phylogenetic relationship among A. terreus isolates inferred by ISSR fingerprints using the Neighbor joining algorithm. The tree is rooted with the outgroup Aspergillus fumigatus. Bootstrap values above 50% from 1000 iterations are noted on nodes. Lines indicate isolate affiliation with clusters defined by STRUCTURE. Filled and open circles and squares indicate geographic origin of isolates.
