Differentially expressed genes upon yieP knock-out. Genes for several ‘general’ acid-resistance responses and/or unknown functions were differentially expressed as consequence of the yieP deletion. Red and blue indicate up-regulation and down-regulation by yieP deletion, respectively. The Y-axis is the log2(fold change) between ΔyieP and the wild-type in the presence of 3-HP, and the X-axis indicates the gene names and their functions.
