Project description:To determine Sigma 54 (SigL) reglons in Bacillus thuringiensis HD73 strain, A sigLmutant, HD(ΔsigL::kan), was constructed with insertion of kanamycin resistance gene cassete. We have employed whole genome microarray expression profiling as a discovery platform to identify the difference of gene expression between mutant and wild-type strains.
Project description:We investigated the gene expression and metabolic regulatory mechanisms associated with the high-level accumulation of ICPs by performing the transcriptomics analysis of B. thuringiensis strain CT-43, using Illumina high throughout sequencing (RNA-seq) technique.
Project description:To determine Sigma 54 (SigL) reglons in Bacillus thuringiensis HD73 strain, A sigLmutant, HD(M-NM-^TsigL::kan), was constructed with insertion of kanamycin resistance gene cassete. We have employed whole genome microarray expression profiling as a discovery platform to identify the difference of gene expression between mutant and wild-type strains. 2 ml samples were separately harvested from B. thuringiensis HD73 and HD(M-NM-^TsigL::kan) strains grown in SchaefferM-bM-^@M-^Ys sporulation medium (SSM) at stages T7 of stationary phase (7 hours after the end of the exponential phase). Three independent repeats were performed for each stain.
Project description:Transcriptional profiling of C. elegans nasp-1 / btr-1 mutant worms versus wild type N2 strain, both exposed to the bacterial pathogen Bacillus thuringiensis DB27.
Project description:Transcriptional profiling of C. elegans nasp-1 / btr-1 mutant worms versus wild type N2 strain, both exposed to the bacterial pathogen Bacillus thuringiensis DB27. One-condition experiment. C. elegans nasp-1 / btr-1 mutant versus N2, exposed to Bacillus thuringiensis DB27. 3 biological replicates, including 1 dye-swaps.
Project description:Comparison in late exponential phase (culture OD600 = 3) of global expression profiles from a Bacillus thuringiensis 407 strain overexpressing transcriptional regulator MogR from xylose inducible vector pHT304-Pxyl, versus an isogenic empty vector control strain, to analyze global expression changes resulting from MogR overexpression
Project description:The transcriptional global profiles of the wild-type strain Bacillus thuringiensis 407 and a cdgF deletion mutant were compared after 1.5 hours of growth in an planktonic culture to analyze the effect of deletion of cdgF, which is involved in c-di-GMP signaling, on the global expression profile of B. thuringiensis 407
Project description:We investigated the gene expression and metabolic regulatory mechanisms associated with the high-level accumulation of ICPs by performing the transcriptomics analysis of B. thuringiensis strain CT-43, using Illumina high throughout sequencing (RNA-seq) technique. The bacterial cells were collected at the time points of 7 h, 9 h, 13 h and 22 h for the whole-genome transcriptomics, respectively.
Project description:Comparison of global expression profiles from a Bacillus thuringiensis 407 strain overexpressing the diguanylate cyclase CdgF (BTB_c06420) from the xylose inducible vector pHT304-Pxyl, versus an isogenic empty vector control strain, to analyze global expression changes resulting from CdgF overexpression
