The condition-dependent transcriptome of Bacillus subtilis 168

ABSTRACT: Recent studies revealed the unsuspected complexity of the bacterial transcriptome but its systematic analysis across many diverse conditions remains a challenge. Here we report the condition-dependent transcriptome of the prototype strain B. subtilis 168 across 104 conditions reflecting the bacterium's life-styles. This data set composed of 269 tiling array hybridizations allowed to observe ~85% of the annotated CDSs expressed in the higher 30% in at least one hybridization and thus provide an excellent coverage of the transcriptome of this bacterium. In addition to the Genbank annotation 1583 new segments of the chromosome were identified as transcribed and have transcription levels reported in the data matrix.

The condition-dependent transcriptome of Bacillus subtilis 168

Project description:Recent studies revealed the unsuspected complexity of the bacterial transcriptome but its systematic analysis across many diverse conditions remains a challenge. Here we report the condition-dependent transcriptome of the prototype strain B. subtilis 168 across 104 conditions reflecting the bacterium's life-styles.

In addition to the Genbank annotation 1583 new segments of the chromosome were identified as transcribed and have transcription levels reported in the data matrix. RNA samples prepared from B. subtilis 168 grown under 104 experimental conditions were reverse transcribed, labeled and hybridized to tiling arrays. Most hybridizations were performed in duplicate or triplicate using RNA isolated from independent cultures. All experiments were performed with strain BSB1 which is a tryptophan-prototrophic (trp+) derivative of the 168 trpC2 strain.

Transcriptomic analysis of VBNC cells of osmostressed Bacillus subtilis 168

Project description:Characterization of the putative genetic determinants of the VBNC state in a known spore-forming Gram-positive organism Bacillus subtilis 168. The VBNC state was induced under osmotic stress and aminoglycoside treatment. The transcriptome landscape of VBNC cells was compared to the viable, antibiotic sensitive B. subtilis cells and to the viable cells with no antibiotic treatment.

Bacillus subtilis 168 moenomycin stimulon

Project description:Transcriptional response of Bacillus subtilis to moenomycin in wild-type 168. Bacillus subtilis 168, WT (-MOE) vs. WT (+MOE). The experiment was conducted in triplicate using three independent total RNA preparations. Untreated samples were labeled with Alexa Fluor 555 and moenomycin treated samples were labeled with Alexa Fluor 647.

Tiling array hybridizations of genomic DNA from Bacillus subtilis 168.

Project description:Genomic DNA prepared from B. subtilis 168 cells grown to stationary phase was hybridized to tiling arrays. The data are used in transcriptome studies to compute expression intensities from raw intensity data using a model of shift and drift and correcting for probe affinity variations as described in (Nicolas et al., 2009, Bioinformatics 25, 2341-2347). B. subtilis 168 was grown in LB medium to stationary phase. Genomic DNA was prepared from four independent cultures. After sonication, DNA was labeled with Cy3 and hybridized to tiling arrays.

Haloarcula hispanica wild-type strain cultured in different media: MG vs 168

Project description:Transcriptional profiling of Haloarcula hispanica wild-type strain cultured in different media comparing MG medium with 168 medium. H. hispanica wild-type strain can accumulate PHBV in MG medium, while can not in 168 medium. Goal was to explore the PHA biosynthesis and its impact on central metabolism in H. hispanica.
