Figure 4

Genes responding to only one dose of γ-ray. Hierarchical clustering of the transcriptional response of S. cerevisiae after exposure to one of three doses of γ-ray (1 Gy, 10 Gy, or 100 Gy) identified 44 genes that showed at least a 3 fold transcriptional response to only one dose of γ-ray. Genes in this figure had at least a 3 fold modulation to one dose and less than a 1.4 fold modulation to all other doses.
