TranscriptomicsR. sphaeroides pRPcrZ vs. R. sphaeroides pR4352 under low oxygen conditions
Transcriptional profiling of R. sphaeroides pRPcrZ compared to control R. sphaeroides pR4352 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 regulat...

Transcriptomics30% O2 vs PS 10W/m2
Comparison of wild-type (2.4.1) R. sphaeroides gene expression in 30% O2 aerobic respiration vs. photosynthesis 10W/m2 light, to identify candidate photosynthesis genes. RNA preparation: pellet cells from exponential phase cultures using 5% phenol in ethanol stop solution; lysozyme + SDS to lyse; p...

TranscriptomicsTranscriptome dynamics during the transition from anaerobic photosynthesis to aerobic respiration in R. sphaeroides
we performed time series microarray analyses to investigate transcriptome dynamics during the transition from anaerobic photosynthesis to aerobic respiration. Published on J. Bacteriol., 190 (1), 286-299, 2008. Major changes in gene expression profiles occurred in the initial 15 min after the shift ...

ProteomicsThree rate-determining protein roles in photosyntheic O2-evolution addressed by time-resolved experiments on genetically modified photosystems
Light-driven water splitting by plants, algae and cyanobacteria is pivotal for global bioenergetics and biomass formation. A manganese cluster bound to the photosystem II proteins catalyzes the complex reaction at high rate, but the rate-determining factors are insufficiently understood. Here we tra...

TranscriptomicsFixK, a universal regulator of microaerobic growth, controls photosynthesis in Rhodopseudomonas palustris
Facultative phototrophic bacteria are excellent models for analyzing the coordination of major metabolic traits including oxidative phosphorylation, photophosphorylation, carbon dioxide fixation and nitrogen fixation. In Rhodobacter sphaeroides and R. capsulatus, a two-component system called RegBA ...

TranscriptomicsMicroarray analysis of laser-microdissected tissues indicates the biosynthesis of suberin in the outer part of roots during formation of a barrier to radial oxygen loss in rice (Oryza sativa).
Internal aeration is crucial for root growth in waterlogged soil. A barrier to radial oxygen loss (ROL) can enhance long- distance oxygen transport via the aerenchyma to the root tip; a higher oxygen concentration at the apex enables root growth into anoxic soil. The ROL barrier is formed within the...

TranscriptomicsThe Transcriptome of Photo-Biological Hydrogen Production in the Green Alga Chlamydomonas reinhardtii
Algal photo-bio hydrogen production, a promising method for producing clean and renewable fuel in the form of hydrogen gas, has been studied extensively over the last few decades. In this study, microarray analyses were used to obtain a global expression profile of mRNA abundance in the green alga ...

ProteomicsMitochondrial alternative NADH dehydrogenases limit ROS, protect chloroplasts and promote survival of reoxygenation in Arabidopsis
Weather extremes are increasing worldwide frequently exposing plants to transient flooding. When floodwaters recede, plants have to cope with increased light intensity and elevated oxygen that favor excessive formation of reactive oxygen species (ROS). We report a novel molecular mechanism that help...

TranscriptomicsRedirection of metabolism for biological hydrogen production
Photosynthetic microbes can produce the clean-burning fuel hydrogen using one of natureâ??s most plentiful resources, sunlight 1,2. Anoxygenic photosynthetic bacteria generate hydrogen and ammonia during a process known as biological nitrogen fixation. This reaction is catalyzed by the enzyme nitrog...
