Cell envelope metabolism in phosphate limited Bacillus subtilis cells

ABSTRACT: Investigation of the whole genome expression level changes in phosphate limited Bacillus subtilis wild-type and delta-phoPR cells Investigation of the whole genome expression level changes of wild-type and delta-phoPR Bacills subtilis cells comparing high and low phosphate medium For each sample analyzed in this study 3 technical replicates were performed. 3 different samples were taken for wild-type cell and delta-phoPR cell, respectively. Samples were taken from exponentially growing cells in high and low phosphate medium as well as from phosphate-limited cells.

Cell envelope gene expression in phosphate-limited Bacillus subtilis cells.

Microbiology (Reading, England) 20110602 Pt 9

The high phosphate content of Bacillus subtilis cell walls dictates that cell wall metabolism is an important feature of the PhoPR-mediated phosphate limitation response. Here we report the expression profiles of cell-envelope-associated and PhoPR regulon genes, determined by live cell array and transcriptome analysis, in exponentially growing and phosphate-limited B. subtilis cells. Control by the WalRK two-component system confers a unique expression profile and high level of promoter activity ...[more]

Expression analysis of sporulating Bacillus subtilis strain 168 deleted for prpE gene

Project description:Investigation of whole genome gene expression level changes in sporulating Bacillus subtilis 168 delta-prpE mutant, compared to the wild-type strain. The mutation engineered into this strain results in impaired germination of spores. A six chip study using total RNA extracted from three separate wild-type cultures of sporulating Bacillus subtilis 168 and three separate cultures of sporulating mutant strain, Bacillus subtilis 168 delta-prpE, in which prpE (yjbP BSU11630) gene coding for a protein phosphatase is deleted entirely. Each chip consists of four fields able to measure the expression level of 4,104 genes from Bacillus subtilis subsp. subtilis strain 168 NC_000964 with eight 60-mer probe pairs (PM/MM) per gene, with two-fold technical redundancy.

A genome-wide analysis of PhoP~P binding to chromosomal DNA reveals several novel features of the PhoPR-mediated phosphate limitation response in Bacillus subtilis

Project description:Identification of the specific PhoP binding regions on the B. subtilis chromosome during exponential and phosphate starvation growth phases. The data serves to extend the PhoPR regulon in Bacillus subtilis and its role in adaptation to phosphate-limiting conditions and cell wall metabolism, as well as implying a role in several other cellular processes. For each sample analyzed in this study three biological replicates were performed. Three different samples were taken from a strain expressing the PhoP-SPA protein as well as from wild-type (168) without a tagged PhoP. Samples were taken from exponentially growing cells in low phosphate medium (LPDM) as well as from phosphate-limited cells (T2). Each sample compares ChIP DNA vs. Total DNA from the same cells.

Expression data from Bacillus subtilis 168 during growth

Project description:The gene expression of Bacillus subtilis 168 showed 3 major patterns including early expression, transition expression and late expression We monitored Bacillus subtilis gene expression by using microarray at differernt time points Bacillus subtilis 168 was choosed as model for gram-positive to study gene expression at different stages

Proteomic response of Bacillus subtilis 3610 to nanoparticles exposition

Project description:The natural biotope of Bacillus subtilis is the upper layer of soil where it grows as a biofilm. To mimic this physiological development and study the impact of nanoparticles during the formation of a biofilm in a contaminated soil, we have studied the proteomic response of the ancestral strain Bacillus subtilis 3610, which is able to form biofilm contrary to the 168 laboratory strain. The bacteria were grown on soft agar plates containing n-ZnO, n-TiO2 or ZnSO4 metal ion.

Probing the regulatory effects of specific mutations in three major binding domains of the pleiotropic regulator CcpA of Bacillus subtilis

Project description:Study the effect of single amino acid point mutations in CcpA at the transcriptome level. Cells were grown in LB with or without 1% glucose and harvested at an OD600 of 0.3 (early exponential phase). Bacillus subtilis strain ccpA::spec carrying pHT304 (empty plasmid), pWH_ccpA_M17R, pWH_ccpA_T62H, or pWH_ccpA_R304W were grown in LB with or without 1% glucose. The control in the microarray study was the strain Bacillus subtilis ccpA::spec carrying pWH_ccpA-wt. All Bacillus subtilis cultures were harvested in the early exponential growth phase at an OD600 of 0.3 from 100 ml culture. Two independent cultures of each strain per growth condition (+/- glucose) and a technical replicate (dye-swap) were used. Please note that '[A}' and '{B}' channels (in the raw data *slide.txt files) correspond to Cy3 (Ch1) and Cy5 (Ch2) in each sample record.

Expression analysis of Bacteroides fragilis NCTC 9343 delta-ungD1 delta-ungD2 delta-PSH acapsular mutant

Project description:Investigation of whole genome gene expression level changes in a Bacteroides fragilis NCTC 9343 delta-ungD1 delta-ungD2 delta-PSH triple mutant, compared to the wild-type strain. The mutations engineered into this strain render it acapsular. The mutants analyzed in this study are further described in Coyne, M. J., M. Chatzidaki-Livanis, L. C. Paoletti, and L. E. Comstock. 2008. Role of glycan synthesis in colonization of the mammalian gut by the bacterial symbiont Bacteroides fragilis. PNAS 105(35):13098-13103 (PID 18723678).
