Growth is inhibited by SHX, not (p)ppGpp. Growth curves of wild-type P. putida KT2440 (yellow circle), ΔrelA mutant (blue triangle) and ppGpp⁰ strain (green square). The vertical dashes delimit the different growth phases defined for the WT strain (see Figure 1). The results obtained from the other biological replicates are shown in Supplementary Figure 4.
