Project description:Ribosome profiling was performed on E. coli wild type cells. All replicates were grown to an OD of ~0.4 in MOPS rich Media with 0.2% glucose supplemented, aerobically in shake flasks. Cultures were treated with chloramphenicol 2 min prior to harvest.

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.
Project description:High-resolution transcriptional profiling of E. coli across nine timepoints of growth in rich media (LB). Samples collected from lag phase to stationary phase of growth. High-resolution tiling array to detect conditional operon isoforms. Custom Agilent array designed to detect condition-specific transcriptional isoforms. Array designed for E coli K12 MG1655 genome. Tiled using 23bp sliding window. Includes >10,000 probes surrounding predicted operon break sites at 6 bp resolution.
Project description:E. coli K-12 MG1655 was grown on M9 minimal media supplemented with 0.2% w/v glucose, fructose, or acetate. The goal of this study was to determine differentially expressed genes in the different media conditions.
Project description:We used RNA-seq to determine differences in RNA levels between wild-type E. coli K-12 and a ΔphoB mutant, each grown in MOPS media with low phosphate (0.2 mM).
