Effect of NaCl concentration on the transcriptional network of E. coli in glucose minimal medium with glycine betaine

ABSTRACT: The growth rate of E. coli decrease continuously with NaCl concentration, however the pattern for metabolic efficiency as measured by optical density is corralated to a change in pattern in transcription data and proteomics.The analysis of the data suggest that between 4.5 and 5% NaCl, the metabolism switched from aerobic to fermentative pathways. The response to osmotic stress is similar to a response to oxidative stress. An example how a stagewise metabolic answer may be the result of continuously increasing stress.

Study of the pattern of gene expression as a function of NaCl concentrations (2%, 3.5% -2 replicates-, 4.5%, 5%, 5.5%). To compare the different conditions, cDNA was normalised to genomic DNA, gDNA.

Transcriptomic analysis of a NaCl-resistant Saccharomyces cerevisiae mutant obtained by evolutionary engineering

Project description:NaCl-resistant Saccharomyces cerevisiae mutant was obtained by evolutionary engineering. EMS mutagenized culture was used as the initial population for the selection procedure. Gradually increasing levels of NaCl stress was applied through 40 successive batch cultivations. The reference strain could not grow even at 0.85 M NaCl whereas this mutant was shown to be resistant up to 1.45 M NaCl concentration. Whole-genome microarray analysis was used to identify the NaCl resistance mechanisms by comparing NaCl-resistant mutant strain and the reference strain in the absence of NaCl stress.

Gene regulation in Bacillus subtilis by the compatible solute glycine betaine

Project description:Glycine betaine (GB) is a potent osmoprotectant for salt stressed Bacillus subtilis cells, which possess three high-affinity uptake systems for GB. OpuA is the dominant transporter for this compatible solute. Northern blot analysis, primer extension experiments and opuA-treA reporter gene fusion studies demonstrated that opuA expression is strongly induced at high osmolality from a single SigA-type promoter. Promoter mutations that improve the match of the opuA promoter to the consensus sequence substantially increase basal-level expression but reduce inducibility by high salinity. Expression of opuA is sensitively controlled by GB, which causes significant repression of opuA transcription at low and high salinity. GB influences the kinetics as well as the final level of high salinity induction of opuA in a concentration-dependent fashion. The repressing effect of GB on opuA transcription requires the intracellular presence of GB, regardless whether it is taken up via OpuA or other transporters or synthesized from choline. Genome-wide transcriptional profiling of salt-stressed B. subtilis cells demonstrated that the repressive effect of GB targets only a subset of high-salinity induced genes. This group of GB-responsive genes comprises in essence the full set of genes with demonstrated functions in either the uptake or synthesis of compatible solutes. Four different samples (untreated, GB, NaCl, and GB + NaCl treated) were analyzed and each sample was hybridized in triplicate.

Response of Leptospirillum ferriphilum DSM14647 to elevated NaCl concentration

Project description:Leptospirillum ferriphilum is an important acidophilic ferrous iron-oxidizing species for bioleaching or biooxidation to win metals like copper or gold, respectively. L. ferriphilum is inhibited by elevated conentrations of chloride. In the present study, the type strain of L. ferriphilum (i.e. strain DSM 14647) by subcultivation in presence of increasing chloride concentrations was adapted to tolerate higher concentrations of NaCl. The adapted culture was grown in presence of 180 mM NaCl or and the non-adapted culture without NaCl, and both were harvested in the late exponential phase. Total RNA was isolated and checked for quality and integrity. For each of the two conditions three RNA preparations of high quality (integrity number above 7) were pooled. Ribosomal RNA was depleted. DNA libraries for paired-end sequencing on an Illumina MiSeq were generated with a TruSeq stranded mRNA library prep kit (Illumina). Among the genes up-regulated were those coding for proteins likely involved in intracellular pH regulation, response to reactive oxygen species, and Fe-S cluster biosynthesis. Among the genes down-regulated in presence of chloride were those related to lipopolysaccharide and peptidoglykane synthesis, and interestingly also those for (hydroxy) ectoine biosynthesis.
