Figure 4. Growth resumption of strains with altered (p)ppGpp levels.

Figure 4

(a) Stationary phase distribution of Crimson expression (0 h) and growth resumption in ΔrelA strain. The distribution of Crimson expression in stationary phase is bimodal (Hartigan’s dip test for unimodality, D = 0.0104, p < 2.2 × 10−16). (b) Growth resumption timing correlates with Crimson expression levels in ΔrelA strain. Time-courses were analysed using linear regression t-test in Graphpad software package and found to be significantly different from each other (p < 0.0001). (c) Stationary phase distribution of Crimson expression (0 h) and growth resumption in ΔrelA ΔspoT strain. The distribution of Crimson expression in stationary phase is bimodal (Hartigan’s dip test for unimodality, D = 0.0175, p < 2.2 × 10−16). (d) Growth resumption timing correlates with Crimson expression levels in ΔrelA ΔspoT strain. Time-courses were analysed using linear regression t-test in Graphpad software package and found to be significantly different from each other (p < 0.0001). Values are an average from three independent experiments and error bars indicate s.e.m.
