FIG. 8.

Effect of growth temperature on cell volume in V. angustum wild-type (S141) and rpoE mutant (EH1) strains. Pictured is a comparison of cell area measurements for the V. angustum wild type (white bar) and rpoE mutant strain (black bar) grown at 25°C (A) and 30°C (B). The results presented are the mean values of three independent experiments, with each data point representing 400 measurements. The asterisk indicates cell area measurements with statistically significant differences (P < 0.05) between the V. angustum wild type (S141) and rpoE mutant strain (EH1), as determined by a three-factor analysis of variance.
