We chose to start with examination of the rpoS gene since , among gram-negative bacteria , many genes are regulated by RpoS .
Consistent with a role for RpoS in the regulation of the KatN protein was not produced in the Salmonella rpoS Fig. 2A .
Consistent with a role for RpoS in the regulation of the KatN protein was not produced in the Salmonella rpoS mutant SL1344K .
The increased sensitivity of the rpoS minus mutant suggests a role for RpoS-controlled gene expression for the higher resistance of stationary-phase cells to UV-C .
Investigation of the KatE level in sequence analysis of rpoS genes Spv-genes are expressed during stationary-phase under control of RpoS .
Investigation of the KatE level in strains of rpoS genes Spv-genes are expressed during stationary-phase under control of RpoS .
They suggested that the difference in the CFA synthase level may be the result of different rpoS alleles , since the expression of another RpoS-regulated gene , poxB , was lower in FT1 than ZK126 ( Wang & Cronan , 1994 ) .
Nickerson and Curtiss found that RpoS-regulated genes are essential for colonisation of gut-associated lymphoid tissue despite the fact that the rpoS mutant colonised the gut as eficiently as did the wild-type strain [ 38 ] .
Total rpoS expression is controlled at all levels starting from regulation of RpoS proteolysis .
Total rpoS expression is controlled at all levels starting from regulation of RpoS proteolysis .
An isogenic rpoS mutant strain of rpoS and a pACYC/rpoS-complemented strain ( rpoS ) were included as controls for RpoS activity .
An isogenic rpoS mutant strain of ATCC 14028 and a pACYC/rpoS-complemented strain ( rpoS ) were included as controls for RpoS activity .
Negative control by RpoS appears to result in the selection of rpoS mutants in bacterial populations .
Negative control by RpoS appears to result in a growth advantage of rpoS mutants in bacterial populations .
These results indicate that phoP may control the expression of the rpoS gene ( Table 2 and Fig. 2 ) , as substantiated by previous reports that PhoP controls the expression of the RpoS-regulated spv virulence genes and rpoS gene ( Heithoff et al. , 1997 ; Tu et al. , 2006 ) .

Presumably , the posttranscriptional mechanisms responsible for regulation of RpoS protein expression were sufficiently robust to withstand our attempts at overwhelming them through ectopic transcriptional upregulation of the rpoS gene .
To verify the role of RpoS in the regulation of entry of KLX2 into the VBNC state , the rpoS gene was deleted in KLX2 DrpoS , KLX6 strain .
To verify the role of RpoS in the regulation of entry of KLX2 into the VBNC state , the rpoS gene was deleted in KLX2 .
Since rpoS is regulated at multiple levels , we determined whether the changes in the rpoS transcription also lead to changes in RpoS accumulation .
