Figure 1.
Genome-wide expression changes on deletion of chromatin and transcription regulators in S. cerevisiae and S. paradoxus. Expression of mutant strains was measured in dye-swap biological repeats with two-species microarrays (Tirosh et al, 2009b). Shown are the genome-wide correlations between the log2 expression ratios (mutant (Δ)/WT) of all samples, with adjacent samples reflecting biological repeats.
