" Upon transition to stationary phase, at least four promoters are activated to transcribe rpoS, including rpoSp1, which is located 550 bp upstream from rpoS within nlpD and is responsible for most rpoS transcription in gene fusion systems (Takayanagi et al. 1994; Lange et al. 1995)."
"A positive correlation between ppGpp and sigma^sup S^ levels has been observed, and the central role played by ppGpp in transcriptional control during starvation (Chesbro 1988) suggested that it influenced transcription of rpoS (Gentry et al. 1993). Subsequently, this was confirmed using transcriptional fusions and measurements of rpoS mRNA levels (Lange et al. 1995)."

"we demonstrate that the expression of both transcriptional and translational rpoS::lacZ fusions as well as the level of rpoS mRNA originating at rpoSp1 is strongly reduced in ppGpp-deficient relA spoT mutants. However, experiments with the 5 deletion constructs indicate that a lack of ppGpp does affect transcriptional elongation rather than initiation"
"our results indicate that apart from the two relatively weak and non-growth-phase-regulated nlpD promoters, there is just one promoter (rpoSp1) within the nlpD structural gene and that this promoter is responsible for the increased transcription of rpoS during the entry into stationary phase in cells grown in rich LB medium"
