Rhodobacter sphaeroides 2.4.1 pPos19 versus pBBR under singlet oxygen stress

Project description:To learn more about the function of Pos19, we constructed an over-expression strain. For this purpose, the Pos19 gene together with its native RpoE promoter was cloned into the middle-copy plasmid pBBR1 and expressed in the R. sphaeroides wild-type 2.4.1 background. The corresponding strain consequently exhibits a singlet oxygen-induced Pos19 over-expression compared to an empty vector control. Total RNA from the over-expression (pPos19) and from the empty vector control (pBBR) strain was extracted after 7 min of singlet oxygen stress and used for microarray analysis to investigate Pos19-induced changes on transcriptome level.

Rhodobacter sphaeroides 2.4.1 pSurS versus pBBR under singlet oxygen stress.

Project description:To learn more about the function of SurS, we constructed an over-expression strain. For this purpose, the surS gene together with its native RpoE promoter was cloned into the middle-copy plasmid pBBR1 and expressed in the R. sphaeroides wild-type 2.4.1 background. The corresponding strain consequently exhibits a singlet oxygen-induced SurS over-expression compared to an empty vector control. Total RNA from the over-expression (pSurS) and from the empty vector control (pBBR) strain was extracted after 7 min of singlet oxygen stress and used for microarray analysis to investigate SurS-induced changes on transcriptome level. RNA samples collected after 7 min of singlet oxygen stress were analyzed by two-color microarrays. Each microarray contains a pool of three independent biological replicates for each sample.

Rhodobacter sphaeroides 2.4.1 pRKSorX144 versus pRK415 under singlet oxygen stress.

Project description:To learn more about the function of SorX, we constructed an over-expression strain. For this purpose, the sorX gene together with its 28-bp upstream region was cloned into the over-expression vector pRK4352 and expressed in the R. sphaeroides wild-type 2.4.1 background. The corresponding strain consequently exhibits a SorX over-expression that is driven by the constitutive 16S rRNA (RSP_4352) promoter. The over-expression strain was compared to an empty vector control (pRK415). Total RNA from the over-expression (pRKSorX144) and from the empty vector control (pRK415) strain was extracted after 7 min of singlet oxygen stress and used for microarray analysis to investigate SorX-induced changes on transcriptome level.

R. sphaeroides Δlov vs. R. sphaeroides 2.4.1 (singlet oxygen stress, aerobic conditions)

Project description:Transcriptional profiling of R. sphaeroides Δlov compared to control R. sphaeroides 2.4.1 under singlet oxygen stress, aerobic conditions Two-strain experiment with overnight cultures of the wild type 2.4.1 and the Δlov mutant. Both were diluted to an OD660 of 0.2 and gassed to adjust aerobic conditions (≈ 170 µM O2). 0.2 µM of methylene blue was added to the cultures to act as photosensitizer. After one doubling time of growth in the darkness cells were illuminated with 800 W m-2 of white light for 7 min.

Role of a short LOV protein in blue light- and singlet oxygen-dependent gene regulation in Rhodobacter sphaeroides

Project description:The facultatively photosynthetic bacterium Rhodobacter sphaeroides harbors an unusual LOV (light, oxygen, voltage) domain protein, RsLOV. While showing a characteristic photocycle, the protein misses a C - terminal output domain, similar to PpSB2 in Pseudomonas putida. Oxygen tension and light quantity are the two main responsible factors controlling the expression of photosynthesis genes in Rhodobacter sphaeroides. Two photoreceptor proteins are known to be involved in this regulation: the intensively studied AppA protein and the more recently identified cryptochrome-like protein CryB. Here we show by transcriptome and physiological studies that RsLOV is also involved in the regulation of photosynthetic gene expression. Our data further hint to a connection between RsLOV and the carbon hydrate metabolism, chemotaxis, as well as to the cellular response to photooxidative stress. RsLOV does not only affect blue light dependent gene expression but also redox-dependent regulation. This SuperSeries is composed of the following subset Series: GSE33194: R. sphaeroides ?lov vs. R. sphaeroides 2.4.1 (microarobic conditions) GSE33259: R. sphaeroides ?lov vs. R. sphaeroides 2.4.1 (blue light, semiaerobic conditions) GSE33260: R. sphaeroides ?lov vs. R. sphaeroides 2.4.1 (singlet oxygen stress, aerobic conditions)

Transcriptome response to nitrosative stress in Rhodobacter sphaeroides 2.4.1

Project description:DNA microarray analysis was employed to investigate the transcriptome response to nitrosative stress in a non-denitrifying facultative photosynthetic bacterium Rhodobacter sphaeroides 2.4.1. We focused on the role played by a nitric oxide-response transcriptional regulator NnrR in the response. The transcriptome profiles of R. sphaeroides 2.4.1 and its nnrR mutant before and after exposure to nitrosating agents S-nitrosoglutathione (GSNO) or sodium nitroprusside (SNP) under semiaerobic conditions were analyzed.
