Gene expression analysis of rel knockout and dcpA knockout strains of Mycobacterium smegmatis MC2 155

ABSTRACT: The experiment was carried out to study the effect of loss of (p)ppGpp or cyclic di-GMP on the gene expression pattern of Mycobacterium smegmatis MC2 155 strains. The cells were cultured in MB7H9 broth containing 0.2% glycerol and 0.05% Tween 80. The transcriptome analysis was performed using GeneSpring GX12 software. Fold changes were calculated with respect to the median expression of wild type replicates. The number of differentially expressed genes (p <0.1) in rel knockout were 417 whereas those in dcpA knockout were 149. Earlier studies had shown that rel knockout and dcpA knockout had shown lower levels of glycopeptidolipids and polar lipids in the cell wall. The microarray data also corraborates our current findings.

RNA deep sequencing data of the whole transcriptomes of the aa3 mutant, aa3 mprA double mutant, and aa3 rel double mutant strains of Mycobacterium smegmatis MC2 155

Project description:To identify the effect of additional deletion of rel and mprA in the aa3 mutant strain lacking the aa3 cytochrome c oxidase of the respiratory electron transport chain of Mycobacterium smegmatis MC2 155, we constructed the aa3 rel double mutant and aa3 mprA double mutant and profiled the transcriptomes of the aa3 mutant, aa3 mprA double mutant and aa3 rel double mutant strains. Our comparative RNA sequencing analysis revealed that expression of most ribosomal proteins was induced in the aa3 rel double mutant and aa3 mprA double mutant relative to the aa3 mutant.

Analysis of gene expression in the rel- + relA+ and rel- + relAE335Q strains of Synechococcus elongatus PCC7942 with RNA sequencing during constant light conditions

Project description:We investigated the role of the basal levels of ppGpp in Synechococcus elongatus PCC7942 in constant light. We performed RNA-seq experiments using the rel- + relA+ and rel- + relAE335Q strains and show that basal levels of ppGpp are required for regulation of global transcription in light.

Analysis of gene expression in the rel- relA+ and the rel- relAE335Q strain of Synechococcus elongatus PCC7942 - RNA sequencing during exposure to darkness (cells grown in light/dark conditions)

Project description:We investigated the role of basal ppGpp levels in Synechococcus elongatus PCC7942 in adaptation to darkness. We performed RNA-seq experiments using the rel- relA+ and the rel- relAE335Q strain at dusk and during exposure to 12 h of darkness. We show that basal ppGpp levels is not sufficient for restoration of appropriate transcriptional shutdown in response to darkness.

Analysis of gene expression in the wild type and rel- strains of Synechococcus elongatus PCC7942 with RNA sequencing during constant light conditions

Project description:Rel is an enzyme involved in the metabolism of ppGpp. We investigated the role of ppGpp in Synechococcus elongatus PCC7942 in constant light and after exposure to darkness. We performed RNA-seq experiments using the rel- strain and wild type and show that ppGpp is required for regulation of global transcription in light and in darkness.
