Fig 7. Effect of rpoS on membrane permeability and relative fitness of S. marcescens 1912768R and the ΔrpoS mutant.

Fig 7

(A-B) Growth of the 1912768R and ΔrpoS mutant strains on 96-well plates containing SDS or Cm. (C) Change in transcript levels of luxS and porin-related genes (n = 4). (D-E) Effect of rpoS on the fitness of S. marcescens. S. marcescens 1912768R with theΔrpoS mutant at a 1:1 ratio and grown for 24 and 48 h in LB or M9 medium. Samples were removed, diluted and plated on LBA plates for CFU determination. The number of 1912768R and ΔrpoS mutant colonies was verified by the different color of the colonies. Mean and SD are shown. *, P < 0.05; **, P < 0.01.
