The result of DNA chip analysis for sigma factors. Putative RNA polymerase sigma factors (SCO0414; sigB, SCO0600; SCO0803; SCO0942; SCO1723; SCO1876; SCO2639; SCO2954; SCO3323; SCO3450; sigT, SCO3892; SCO4005; SCO4409; SCO4452; sigQ, SCO4908; SCO4996; SCO7099; SCO7192; SCO7314; sigG, SCO7341), hypothetical regulatory protein (SCO0542), conserved hypothetical proteins (SCO0675, SCO4757), putative anti sigma factor antagonists (SCO3692, SCO0781, SCO7323, SCO7754), probable ECF-family sigma factors (SCO0864, SCO5147), RNA polymerase principal sigma factors (hrdC, SCO0895; hrdD SCO3202), putative RNA polymerase ECF sigma factors (SCO1263, SCO3709, SCO4146, SCO4866, SCO4996), putative membrane protein (SCO3362), putative regulatory protein (SCO3691), putative anti anti sigma factor (SCO4410), RNA polymerase sigma factors (sigR, SCO5216; sigH, SCO5243), major vegetative sigma factor (hrdB, SCO5820), and putative anti-sigma factor (SCO7322) were upregulated in the pH-shocked culture, while putative RNA polymerase sigma factors (SCO0255; SCO2742; SCO5934; SCO6239; SCO7104), putative anti-sigma factor antagonists (SCO0672; SCO4027; SCO7619), probable ECF-family sigma factor (SCO0866), putative integral membrane protein (SCO1632), putative ECF sigma factors (SCO3715; SCO3736; SCO4864; SCO7144), hypothetical protein (SCO4939), RNA polymerase ECF sigma factor (sigJ, 1276), SCP1.161c, and SCP1.116 were downregulated in the pH-shocked culture.
