Project description:Transcriptome profiling of Rhodobacter sphaeroides cells (WT and delta-oxyR mutant) grown in semiaerobic conditions, 7 and 30 min after addition of H2O2 up to 1 mM Keywords: time series
Project description:Transcriptional profiling of R. sphaeroides pRKPcrZ compared to control R. sphaeroides pRK4352 under low oxygen conditions. In this study we compared the transcriptome of a PcrZ over-expression strain to a control strain. PcrZ is the first small non-coding RNA, which is involved in the complex regulatory network of photosynthesis gene regulation in Rhodobacter sphaeroides. It counteracts the formation of photosynthetic complexes in a redox dependent manner.

Project description:mRNA levels were measured in Rhodobacter sphaeroides 2.4.1 at 20% O2 and 0.5% O2, Rhodobacter sphaeroides 2.4.1 App11 (AppA-null), Rhodobacter sphaeroides 2.4.1 (pPNs) and PpsR mutant PPS2-4. The mRNA samples were prepared from cultures supplied with 20% O2, 1% CO2, and 79% N2, and grown in the dark to an OD of 0.18. The mRNA levels for each strain was measured three times.
