03/01/2007 - "Recent studies with Myxococcus xanthus have suggested that homologues of the Escherichia coli heat-shock sigma factor, RpoH, may not be involved in the heat-shock response in this delta-proteobacterium. "
01/01/2013 - "Transcription of the ibpA gene depends on the alternative heat shock sigma factor σ(32). "
12/01/2012 - "Bacteria belonging to the Alphaproteobacteria normally harbour multiple copies of the heat shock sigma factor (known as σ(32), σ(H) or RpoH). "
06/01/2012 - "coli O157 crucial for growth resumption of this human pathogen after heat shock, with specific focus on the role of the RpoS sigma factor. "
01/01/2012 - "The model accurately reproduces changes of gene transcription level observed in polymerase sigma-subunit knockout and heat shock experiments in plant plastids. "
11/01/1996 - "The alternative sigma factor RpoS is a global regulator of gene expression during starvation and stress conditions and is required for virulence in Salmonella spp. We have used lacZ reporter fusions to rpoS and rpoS-dependent genes to study rpoS regulation after entry of Salmonella typhimurium into macrophages and epithelial cells. "
12/01/1992 - "In this study we evaluated the role of KatF, a putative sigma factor for starvation- and stationary phase-induced genes, in the expression of the spvB gene. "
12/01/2014 - "In many Gram-negative bacteria, starvation and other stress responses are regulated by the sigma factor RpoS. "
01/01/2012 - "Lactobacillus sakei, a non-sporulating meat-borne bacterium, carries an alternative sigma factor seemingly orthologous to σ(H) of Bacillus subtilis, best known for its contribution to the initiation of a large starvation response ultimately leading to sporulation. "
08/01/2010 - "Here we show that polyphosphate accumulated during nutrient starvation directly targets transcriptional machinery by binding to the principal sigma factor in H. "

11/01/1999 - "In the present study, we provide evidence that the groESL, hrcA-grpE-dnaK and cbpA-hspR-orf operons encoding the major chaperones of the human gastric pathogen Helicobacter pylori are transcribed by the vegetative sigma factor sigma80 and are regulated negatively by the transcriptional repressor HspR. "
07/01/2008 - "The upstream region of the Tn5-mutated ORF contained another ORF that encoded an extra-cytoplasmic function (ECF)-class sigma factor (sigma(E), RpoE). "
07/01/2008 - "Cloning and sequencing of the Tn5 flanking region in both the carotenoid-producing mutants of Sp7 revealed insertion of Tn5 in an ORF encoding anti-sigma factor, a ChrR-like protein. "
12/01/2004 - "The suppressor consists of a transposon insertion in a previously annotated ORF, here termed hspQ, a novel heat shock gene whose promoter is recognized by the major heat shock sigma factor sigma32. "
10/01/1997 - "An ORF predicted to encode the primary sigma factor SigA was identified downstream of abcB."
04/01/2015 - "Sigma Factor SigB Is Crucial to Mediate Staphylococcus aureus Adaptation during Chronic Infections."
02/01/2014 - "These results indicate that NonA is a novel protein that can abort SP10 infection, and its transcription was regulated by SP10 sigma factor. "
08/01/2013 - "RpoS, an alternative sigma factor, plays a central role in spirochetal adaptation to the mammalian host by governing expression of many genes important for mammalian infection. "
01/01/2012 - "We evaluated the contribution of the extracytoplasmic function sigma factor σ(E) for Corynebacterium pseudotuberculosis resistance to stress conditions resembling those found intracellularly during infection. "
01/01/2012 - "The alternative sigma factor B modulates virulence gene expression in a murine Staphylococcus aureus infection model but does not influence kidney gene expression pattern of the host."
01/01/2015 - "tuberculosis, 10 are regarded as the ECF sigma factor that exerts their attributes in various stress response. "
11/26/2013 - "tuberculosis protein, PDZ-interacting protease regulator 1 (Ppr1), which bridges between the Rip1 PDZ domain and anti-sigma factor M (Anti-SigM), a Rip1 substrate, but not Anti-SigK or Anti-SigL, also Rip1 substrates. "
08/01/2010 - "tuberculosis intramembrane protease Rip1 controls transcription through three anti-sigma factor substrates."
04/16/2010 - "tuberculosis sigma factor sigma(L) regulates the expression of genes involved in cell-wall and polyketide syntheses. "
03/01/2009 - "tuberculosis employs an exquisite cascade consisting of the cognate anti-sigma factor UsfX and anti-anti sigma factors RsfA and RsfB to regulate the functions of the alternate sigma factor SigF. "
