(Submitter supplied) Exposure to oxygen and light generates photooxidative stress by the bacteriochlorophyll a mediated formation of singlet oxygen (1O2) in the facultative photosynthetic bacterium Rhodobacter sphaeroides. We have identified SorY as an sRNA, which is induced under several stress conditions and confers increased resistance against 1O2. SorY by direct interaction decreases the levels of takP mRNA, encoding a TRAP-T transporter. more...

(Submitter supplied) Global transcriptome analyses at different stages of growth were applied to monitor growth phase-dependent gene expression in the alpha-proteobacterium Rhodobacter sphaeroides. Cultures with low aeration, which underwent strong changes in levels of dissolved oxygen during growth, were compared to aerated cultures, which showed little variation in levels of dissolved oxygen. Cells were in stationary phase for 12 h or for 57 h before dilution into fresh medium. more...

(Submitter supplied) We integrated genomic and transcriptomic analysis of a newly isolated obligate Methylomonas sp. DH-1 grown on methane and methanol. Comparative transcriptomic analysis between methane and methanol as a sole carbon source revealed different transcriptional responses of Methylomonas sp.

(Submitter supplied) By integrating sequence information from closely related bacteria with a compendium of high-throughput gene expression datasets, a large-scale transcriptional regulatory networks was constructed for Rhodobacter sphaeroides. Predictions from this network were validated in part using genome-wide analysis for 3 transcription factors (PpsR, RSP_0489 and RSP_3341).

(Submitter supplied) Rhodobacter sphaeroides is the best studied photosynthetic bacterium, yet much remains unknown about its transcriptional regulatory processes on a genome-scale. We developed a work-flow for genome-scale reconstruction of transcriptional regulatory networks and applied it to sequence and gene expression data sets available for R. sphaeroides. To assess the predictive performance of our reconstructed model, we generated global transcript level and/or protein-DNA interaction data for 3 transcription factors (PpsR, RSP_0489 and RSP_3341). more...

(Submitter supplied) In this study, we performed a ChIP-chip experiment to determine the regulon of FnrL in Rhodobacter sphaeroides. We grew R. sphaeroides under anaerobic photosnthetic conditions, in which FnrL is expected to bind DNA and contol gene expression, and immuno-precipitated FnrL, but also sigma70 and the Beta' subunits of RNA polymerase to determine transcription activity.

(Submitter supplied) Malic enzymes decarboxylate the tricarboxylic acid (TCA) cycle intermediate malate to the glycolytic end-product pyruvate and are well positioned to regulate metabolic flux in central carbon metabolism. The bacterium Sinorhizobium meliloti has a NAD(P)-malic enzyme (DME) and a NADP-malic enzyme (TME) and DME is required for symbiotic N2-fixation. To help understand the role of these enzymes, we examined growth, metabolic and transcriptional consequences resulting from the deletion of these enzymes. more...

(Submitter supplied) The order Rhizobiales contains numerous agriculturally, biotechnologically, and medically important bacteria including the rhizobia, Agrobacterium, Brucella, and Methylobacterium, among others. These organisms tend to be metabolically versatile, but there has been relatively little investigation into the regulation of their central carbon metabolic pathways. Here, RNA-seq and promoter fusion data are presented to show that the PckR protein is a key regulator of central carbon metabolism in Sinorhizobium meliloti; during growth with gluconeogenic substrates, PckR represses expression of the complete Entner-Doudoroff glycolytic pathway and induces expression of the pckA and fbaB gluconeogenic genes. more...

(Submitter supplied) Investigation of whole genome expression changes in Magnetospririllum magneticum mutants, probing the role of the CtrA regulatory pathway. The mutants are further described in a manuscript submitted for publication at J. Bacteriology. Developmental events across the prokaryotic life cycle are highly regulated at the transcriptional and post-translational levels. Key elements of a few regulatory networks are conserved among phylogenetic groups of bacteria, although the features controlled by these conserved systems are as diverse as the organisms encoding them. more...

Although, genetically different, these TF were functionally very similar. When first identified these TFs were named AraQ and MalR1, due to their predicted associations with arabinose and maltose metabolism, respectively. more...
