FIG. 4.

NJ tree generated from the alignment of Penicillium spp. ITS1 sequences (188 to 201 bp). Sequences and accession numbers of selected organisms retrieved from GenBank appear in boldface. Samples numbering corresponds to DGGE bands in Fig. 1 and 2. Bootstraps values >60% are indicated at branch nodes. ITS1 sequence from Eurotium repens (AY373890) was used as outgroup. Origin of sequences is depicted by shaded dots on the right side of each name: white, control discs; gray, TCA tainted discs; black, cork stoppers.
