▪ Abstract The promoter recognition specificity of Escherichia coli RNA polymerase is
modulated by replacement of the σ subunit in the first step and by interaction with …

Throughout their life, bacteria need to sense and respond to environmental stress. Thus,
such stress responses can require dramatic cellular reprogramming, both at the …

Nitrogen regulatory protein C (NtrC) of enteric bacteria activates transcription of
genes/operons whose products minimize the slowing of growth under nitrogen-limiting …

The σS subunit of RNA polymerase, the product of the rpoS gene, controls the expression of
genes responding to starvation and cellular stresses. Using gene array technology, we …

The alternative sigma factor RpoS controls the expression of many stationary-phase genes
in Escherichia coli and other bacteria. Though the RpoS regulon is a large, conserved …

Borrelia burgdorferi (Bb) adapts to its arthropod and mammalian hosts by altering its
transcriptional and antigenic profiles in response to environmental signals associated with …

Bacterial biofilms have great significance for public health, since biofilm-associated
microorganisms exhibit dramatically decreased susceptibility to antimicrobial agents and …

Multidrug efflux is an obstacle to the successful treatment of infectious diseases, and it is
mediated by multidrug efflux pumps that recognize and export a broad spectrum of …

Cinnamaldehyde (CAD) derived from cinnamon bark has received much attention for its
potential as a nematicide and food additive. Previously, we have succeeded in developing …

Lacide 3-indole acétique (IAA), une phytohormone, s' accumule dans le milieu de culture du
Pseudomonas putida GR12-2, une bactérie favorisant la croissance des végétaux mais …
