Figure 6From: The role of sigma factor RpoH1 in the pH stress response of Sinorhizobium melilotiM-values of specific genes throughout the time-course following acidic pH shift in S. meliloti 1021 wild type strain (closed squares) and sigma factor rpoH1 mutant (open squares). Graphics A and B exemplify RpoH1-independent up and downregulation, respectively, whereas graphics D and E show RpoH1-dependently regulated genes. C and F account for complex RpoH1-dependent downregulation in the later time points following acidic shift.Back to article page
