A. Effect of ppGpp and M+ suppressor mutations on viability on MMS and NFZ plates. The strains are from left to right: GTN1867, GTN1713, GTN381, GTN1717. Three M+ suppressor mutants were independently isolated from GTN1867.
B. Effect of ppGpp levels on cellular filamentation of the priA300 mutant. Cells were analyzed as described in the legend to Figure 4. The strains are from left to right: GTN1867, GTN1713, GTN381, GTN1717, GTN1789, GTN1811.
C. Effect of IF2-1 and IF2-2/3 expressed from a plasmid vector on the cellular filamentation of the priA300 mutant. The strains are from left to right: GTN1860, GTN1858, GTN1856, GTN1800, GTN1757, GTN1759.
