Project description:Expression profiles of wild-type and SgrR mutant E. coli strains under aMG and 2-DG-induced stress. Expression profiles of E. coli overexpressing SgrS sRNA. Illumina RNA-Seq of total RNA extracted from wild-type, SgrR/SgrS mutant and SgrS overexpressing E. coli strains grown in different conditions.
Project description:We investigate sigma factor binding regions for each sigma factor under various enviromental and/or genetic conditions. To measure sigma factor binding at a genome scale, we employed a ChIP-chip method to derivative strains of E. coli K-12 MG1655 wild type and its isogenic rpoS and rpoN knock-out strains under various conditions.
Project description:Mature tRNA pools were measured using an adaptation of YAMAT-seq (Shigematsu et al., 2017; doi:10.1093/nar/gkx005 ) and further described in (Ayan et al., 2020; doi:10.7554/eLife.57947) in 10 strain-medium combinations (all strains dervied from the model bacterium E. coli MG1655). The aim of the experiment was to investigate the effect of reducing tRNA gene copy number on mature tRNA pools in rich and poor media.

To measure sigma factor binding at a genome scale, we employed a ChIP-chip method to derivative strains of E. coli K-12 MG1655 wild type and its isogenic rpoS and rpoN knock-out strains under various conditions. A 45 ChIP-chip study under 4 separate culture conditions. The high-density oligonucleotide tiling arrays used were consisted of 371,034 oligonucleotide probes spaced 25 bp apart (25-bp overlap between two probes) across the E. coli genome.
Project description:We report the application of single-molecule-based sequencing technology for high-throughput profiling of transcription start sites for Escherichia coli under different conditions. By obtaining sequence from 5' RACE (rapid amplification of cDNA ends) followed by deep sequencing, we generated genome-wide TSS (transcription start site) maps for E. coli. This TSS-map was integrated with ChIP-chip data generated for 6 sigma factors in E. coli, resulting in reconstruction of sigma factor network in E. coli.
