Rok regulates yuaB expression during architecturally complex colony development of Bacillus subtilis 168.

Kovács Akos T AT Kuipers Oscar P OP

Journal of bacteriology 20101119 4

Transcriptome analysis of a Bacillus subtilis rok strain that showed reduced complex colony structure formation revealed significant downregulation of the yuaB gene. Overexpression of yuaB restored structure formation in the rok strain. We show that transcription of yuaB is indirectly regulated by Rok, independently from its previously described AbrB-dependent regulation. ...[more]

Comparison of Bacillus subtilis wild type and cshA mutant at exponential versus stationary phase

Project description:Comparison of Bacillus subtilis wild type and cshA mutant at exponential versus stationary phase. Detailed description (other than provided below) of growth conditions, RNA preparation, cDNA synthesis and hybridization conditions can be found in the submitted paper. Bacillus subtilis 168 wild type and its cshA derivative strain were grown in CSE-Glu medium and cells were harvested at mid exponential (OD600 ~0.8) and early stationary phase (OD600 ~2.2-2.4). For both time points, 4 biological replicates were used and 2 were mixed after cDNA labeling, resulting 2 slides for both exponential and stationary phase. Dye swaps are included in both experiments.

Effect of floT and floA mutations on the global transcriptome of Bacillus subtilis NCIB3610

Project description:To compare the altered transcript levels in the floT, floA single and floTfloA double mutants of Bacillus subtilis, cells were grown in MSgg medium until the late exponential phase and their transcriptome was compared to the wild type, NCIB3610 strain. Bacillus subtilis NCIB3610 wild type and its floT, floA, and floTfloA mutants strain were grown in MSgg medium and cells were harvested at late exponential (OD600 ~1.0-1,2) phase. 3 biological replicates were used, resulting 3 slides for each mutant strain. Dye swaps are included in both experiments.
