Response in Shewanella oneidensis MR-1 and so2426 deletion mutant to Hexavalent Chromium over a 24 hour period

ABSTRACT: Shewanella oneidensis MR-1 exhibits diverse metal ion-reducing capabilities and thus is of potential utility as a bioremediation agent. Knowledge of the molecular components and regulatory mechanisms dictating cellular responses to heavy metal stress, however, remains incomplete. In a previous work, the S. oneidensis so2426 gene, annotated as a DNA-binding response regulator, was demonstrated to be specifically responsive at both the transcript and protein levels to acute chromate [Cr(VI)] challenge. To delineate the cellular function of SO2426 and its contribution to metal stress response, we integrated genetic and physiological approaches with a genome-wide screen for target gene candidates comprising the SO2426 regulon. Keywords: Time course

Quantitative proteome of Shewanella oneidensis MR-1

Project description:We investigated the anode-specific responses of Shewanella oneidensis MR-1, an exoelectroactive ammaproteobacterium, using for the first time iTRAQ and 2D-LC MS/MS driven membrane proteomics to compare protein abundances in S. oneidensis when generating power in MFCs, and growing in a continuous culture.

Expression data from Shewanella oneidensis MR-1 in time series experiment

Project description:The sumitted data compares gene expression profile of Shewnaella oneidensis MR-1 on two different sets of media conditions (nutritionally rich LB medium and Lactate minimal medium) To explore the effect of various growth phases in Shewanella oneidensis MR-1, the genome-wide transcriptome profiles growth in two sets media was compared to each other. Strain was grown in chemostat at 20% O2 in batch culture. Samples were collected in duplicate from both experiments.

dRNA-seq of Shewanella oneidensis MR-1

Project description:We combined high-resolution tiling microarrays and 5'-end RNA sequencing to obtain a genome-wide map of transcription start sites (TSSs) for Shewanella oneidensis MR-1. To test the reliability of these TSSs, we compared our result to those from differential RNA sequencing (dRNA-seq), which discriminates primary and processed ends of transcripts. We found that our identified TSSs tend to have significantly more mapped reads in the TEX(+) sample than the TEX(-) sample. Overall, the dRNA-seq results support the validity of our predictions for TSS. S. oneidensis MR-1 was grown to mid-log phase in Luria-Bertani broth (LB) or defined lactate minimal medium, and total RNA was isolated and used for differential RNA-sequencing (dRNA-seq) by next-generation sequencing, which is used to verify genome-wide transcription start sites. For dRNA-seq, total RNA was partially treated with Terminator Exonuclease (TEX) to digest processed RNA and thereby enrich for primary transcript ends.

Transcriptional targets of Shewanella oneidensis HnoC (SO_2540)

Project description:To identify the transcriptional targets of the DNA-binding response regulator HnoC (SO_2540), mRNA transcript levels in Shewanella oneidensis were measured using whole genome microarray analysis. Transcript levels were compared between WT Shewanella oneidensis and a hnoC deletion strain. Transcript levels of a WT and hnoC deletion strain were measured after 15 hrs growth, 4 independent replicates were performed for each strain
