15V-P4 position in the phylogeny of <i>S. cerevisiae</i> strains.

<p>(A) Neighbor joining phylogenetic tree of 95 strains including 15V-P4 inferred from alignment of conservative chromosome regions. (B) Phylogenetic tree of 29 strains including 15V-P4 inferred from sequences of 807 common genes under the GTR+G model and tested with 500 bootstrap replicates. Branch bootstrap values greater than 95 are indicated. In both trees, strain names are colored according to functional origin. Grey circles highlight either the population group (A) or common functional origin (B). Branch lengths are given in the same scale on both trees. PGC, the Peterhof genetic collection.
