Project description:Transcriptional profile of the uppS-RBS (A to C) mutant during log growth phase in LB medium. Bacillus subtilis W168, WT vs. uppS-RBS (A to C). The experiment was conducted two times using three independent total RNA preparations (biological triplicates). Each comparison was performed in dye-swap with the same RNA preparation. For each paried comparison, one sample was labeled with Alexa Fluor 555 and the other was with Alexa Fluor 647.
Project description:Transcriptional profile of the sigA (G336C) mutant during log growth phase in LB medium. Bacillus subtilis W168, WT vs. sigA (G336C). The experiment was conducted two times using three independent total RNA preparations (biological triplicates). Each comparison was performed in dye-swap with the same RNA preparation. For each paried comparison, one sample was labeled with Alexa Fluor 555 and the other was with Alexa Fluor 647.
Project description:Transcriptional profile of the rpoC G1122D mutant during log growth phase in LB medium. Bacillus subtilis W168, WT vs. rpoC (G1122D). The experiment was conducted two times using three independent total RNA preparations (biological triplicates). Each comparison was performed in dye-swap with the same RNA preparation. For each paried comparison, one sample was labeled with Alexa Fluor 555 and the other was with Alexa Fluor 647.
Project description:Transcriptional profile of the rocG gudB double null mutant during log growth phase in LB medium. Bacillus subtilis W168, WT vs. delta-rocG delta-gudB. The experiment was conducted two times using three independent total RNA preparations (biological triplicates). For each paried comparison, WT was labeled with Alexa Fluor 555 and the rocG gudB double mutant was with Alexa Fluor 647.
Project description:S. typhimurium 14028 wt, hfq and smpB were harvested from log phase LB (LBlog); (2), stationary phase LB (LBstat); (3) 4h MgM medium pH 5.0 after resuspension of LB stat culture (MgMshock); and (4) log phase MgM medium pH5.0 after 100fold dilution of an LB stat culture (MgMDil). Total RNA was extracted, cDNA labeled and hybridized to a non-redundant Salmonella whole genome PCR product ORF array.
Project description:Transcriptomic analysis of Bacillus subtilis wild-type strain and hfq mutant in stationary phase of growth using to tiling array gene expression analysis. RNA-binding protein Hfq is a key component of the adaptive responses of many proteobacterial species. In these organisms, the importance of Hfq largely stems from its participation to regulatory mechanisms involving small non-coding RNAs. In contrast, the function of Hfq in Gram-positive bacteria has remained elusive. 97 transcription units (representing 134 genes) were found significantly different between the wild-type and the ΔhfqBs strains in the stationary cultures performed in rich LB medium.
