Putative introgressed PDR5 gene. (A) Neighbor-joining tree of the PDR5 ORF from 100 S. cerevisiae strains and sibling species with bootstrap values shows two clusters of this sequence. The group 1 cluster containing the putative introgressed PDR5 consists of 14 strains that are both clinical in origin and in the mosaic population. The group 2 cluster consists of sequences from 86 strains including S288c. (B) Comparison of DNA and protein sequences between YJM1133 (with putative introgressed PDR5) and S288c. The tick marks indicate polymorphisms.
