Whole genome sequence of Staphylococcus saprophyticus reveals the pathogenesis of uncomplicated urinary tract infection.
TLDR
The uropathogenicity of S. saprophyticus can be attributed to its genome that is needed for its survival in the human urinary tract by means of novel cell wall-anchored adhesin and redundant uro-adaptive transport systems, together with urease. Expand
Blue light-induced transcription of plastid-encoded psbD gene is mediated by a nuclear-encoded transcription initiation factor, AtSig5.
TLDR
It is proposed that AtSig5 acts as a mediator of blue light signaling that specifically activates the psbD BLRP in response to blue light in Arabidopsis. Expand
The mammalian ionic environment dictates microbial susceptibility to antimicrobial defense peptides
TLDR
Findings show that changes in cell wall thickness and Sigma factor B expression correspond to the increased susceptibility to the AMP LL‐37, and suggest that discovery of new antimicrobials should specifically target pathogens as they exist in the host and not the distinctly different phenotype of bacteria grown in culture broth. Expand
Novel nuclear‐encoded proteins interacting with a plastid sigma factor, Sig1, in Arabidopsis thaliana 1
TLDR
The discovery of the nuclear encoded protein (SibI) that is transported into chloroplasts and interacts specifically with the region 4 of Sig1 in Arabidopsis suggests the transcriptional regulation by sigma factor binding proteins to function in the plastids of higher plant. Expand
A new staphylococcal sigma factor in the conserved gene cassette: functional significance and implication for the evolutionary processes
TLDR
This work examined the S. aureus genome with a special attention to the gene arrangement around the sigma factor genes of a close relative, B. subtilis, to search for possible sigmaFactor genes. Expand
Blue light specific and differential expression of a plastid σ factor, Sig5 in Arabidopsis thaliana
TLDR
It is found that blue light extensively induced the accumulation of SIG5 transcripts, but red light did not and the blue light specificity was not observed in the accumulations of remaining five SIG genes. Expand

TLDR
In this study, 100S ribosome formation in six species of Gammaproteobacteria and eight species belonging to other bacterial classes was compared and it was found that ribosomes formed by long HPF were much more stable than those formed by RMF and short HPF. Expand
Staphylococcus aureus requires cardiolipin for survival under conditions of high salinity
TLDR
CL is not essential for S. aureus growth under conditions of high salinity, but is necessary for survival under prolonged high-salt stress and for the generation of L-form variants. Expand
Expression of a Cryptic Secondary Sigma Factor Gene Unveils Natural Competence for DNA Transformation in Staphylococcus aureus
TLDR
A unique model for staphylococcal competence regulation by SigH is proposed that could help explain the acquisition of antibiotic resistance genes through horizontal gene transfer in this important pathogen. Expand
Overexpression of Sigma Factor, ςB, Urges Staphylococcus aureus to Thicken the Cell Wall and to Resist β-Lactams
TLDR
The constructed over expressed sig B knock-out mutant suggests that sig B plays some important roles in cell wall synthesis and in resistance to antibiotics that perturb thecell wall synthesis. Expand
