Relative mRNA abundance of genes upregulated during sigD overexpression. Relative abundance of mRNA of each gene was quantified by real-time PCR. The white and gray columns show the abundance in WT(pVWEx1-sigD) without IPTG (0 μM IPTG), and in WT(pVWEx1-sigD) with 50 μM of IPTG (50 μM IPTG), respectively. Error bars represent standard deviations calculated from biological triplicates. The p-value of mRNA abundance was calculated by Student’s t-test (two-tail, unpaired) between 0 μM and 50 μM of IPTG, and is shown by *, ** and *** for <0.05, <0.01 and <0.001, respectively
