Fig. 2: Transcriptomic changes from penicillin exposure over time.

A Pyrimidine biosynthesis pathway. B Purine biosynthesis pathway. C genes involved in both nucleotide biosynthetic pathways. See Methods for details. Data presented are all genes that were scored as significantly differentially regulated, with a cut-off p-value < 0.05. Numbers within the heat map represent raw log2 fold-change.
