Project description:Transcriptome comparison of Bacillus subtilis Natto under sliding permissive (0.7% agar) and restrictive (1.5% agar or spo0A mutant strain) conditions.
Project description:Investigation of the kinetics of whole genome gene expression level changes in Bacillus subtilis NDmed strain during formation of submerged biofilm and pellicle. The Bacillus subtilis NDmed strain analyzed in this study is able to form thick and highly structured submerged biofilms as described in Bridier et al., (2011) The Spatial Architecture of Bacillus subtilis Biofilms Deciphered Using a Surface-Associated Model and In Situ Imaging. PLoS ONE 6(1):e16177.
Project description:Identification of the specific WalR (YycF) binding regions on the B. subtilis chromosome during exponential and phosphate starvation growth phases. The data serves to extend the WalRK regulon in Bacillus subtilis and its role in cell wall metabolism, as well as implying a role in several other cellular processes.
Project description:Transcriptional response of Bacillus subtilis KS002 to targocil Strain KS002 (Bacillus subtilis PY79 M-NM-^TtagGHBs::cat, amyE::Phyperspank tarGHSa spc) is a targocil sensitive B. subtilis strain, with TarGH from Staphylococcus aureus as the only WTA exporter, IPTG dependent (Schirner, Stone and Walker, ACS Chem Bio 2011). Strain KS002 was treated with or without targocil for 30 min. Each experiment was conducted three times using three independent total RNA preparations (biological triplicates). For each paried comparison, one sample was labeled with Alexa Fluor 555 and the other was with Alexa Fluor 647. For each comparison, one replicate was performed with dyeswap with the same RNA.
Project description:Bacillus subtilis is exposed to a wide range of transitory stress and starvation conditions. Here we investigate the expression changes observed in the B. subtilis wild type strain 168 and its isogenic sigB mutant(BSM29) with respect to each stress condition tested.
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.
