Figure 1.

S. cerevisiae–S. kudriavzevii interspecific hybrids. aCGH data for all S. kudriavzevii probes are shown, with strain names along the top; for comparison, hybridization of the actual S. kudriavzevii strain to the S. kudriavzevii probes is shown on the left. Hierarchical clustering of the strains was performed using only the S. kudriavzevii probes and the generated dendrogram is shown above the strain names. Probes are shown in order of chromosomal position for the S. kudriavzevii chromosomes (Scannell et al. 2011), with alternating red and blue bands along the side indicating chromosome number. (Red bars) Increased hybridization (increased copy number relative to the pooled reference) to the probes. (Green bars) Decreased relative hybridization (decreased copy number).
