FIG 2.

Effect of ΔdksA on the ability of strains expressing wild-type (WT) or mutant alleles of rpoB to grow on M63 salt-based minimal medium. Strains were first grown on the rich medium (LBA) for 24 h (left two plates). Individual colonies from LBA were then streaked on M63 minimal medium supplemented with glycerol (M63-Gly) and grown at 37°C for 48 h (right two plates). Key genetic characteristics are shown.
