Transcriptional Regulation of the rsbV Promoter Controlling Stress Responses to Ethanol, Carbon Limitation, and Phosphorous Limitation in Bacillus subtilis

Figure 4

Effects of various mutations and conditions on the phosphorous starvation response. (a) Wild-type response (rsbV1, ■) to phosphate limitation, and the effects of the rsbV1m1 (◆), rsbV3 (▴), and rsbV5 (×) mutations on this response as a function of time. (b) Effects of the loss of CcpA (), TnrA (◆), and both transcription factors (▴) as compared with wild type (■) on the phosphate limitation response. (c) Lack of effect of the loss of CcpA () on the phosphate limitation response of the ctc gene which is under sigma B (σ ^B) control. The wild-type response is represented by ■.
