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: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:The gene expression profile of MC4100 delta rsd with pACYC Rsd and pACYC delta BS plasmids has been analysed using whole genome oligonucleotide microarrays. Control RNA was isolated from 50ml LB cultures of MC4100 delta rsd strain with pACYC delta BS. Experimental RNA was isolated from 50ml LB cultures of MC4100 delta rsd with pACYC Rsd, for each growth condition (OD600 = 0.4: log phase, 0.9: late log phase, 1.1: transition phase, ST(OD600 = >2.0): stationary phase). The experiments performed replicate. Keywords: timecourse (overproduction of Rsd)
