Remodeled respiration in ndufs4 with low phosphorylation efficiency suppresses Arabidopsis germination and growth and alters control of metabolism at night.

Respiratory oxidative phosphorylation is a cornerstone of cellular metabolism in aerobic multicellular organisms. The efficiency of this process is generally assumed to be maximized, but the presence of dynamically regulated nonphosphorylating bypasses implies that plants can alter phosphorylation efficiency and can benefit from lowered energy generation during respiration under certain conditions. We characterized an Arabidopsis (Arabidopsis thaliana) mutant, ndufs4 (for NADH dehydrogenase [ubi ...[more]

Transcription profiling of Drosophila after exposure to microgravity in the International Space Station and in a microgravity simulator

Project description:Larvae-Pupae transition flies (Drosophila) were recovered and transport for 3 days at 12-14ºC to arrest development until the launch site, then exposed to RT (18-20ºC) for some hours including the launch and trip to the International Space Station, then pupae were exposed to microgravity in the ISS for 4 days and a half at 22ºC. Finally pupae were fixed on acetone and frozen until recovery on Earth. Four groups of samples: 1 ISS (+ground control) as described, 2 RPM (microgravity simulator on Earth) as described, 3 RPM without constrains (No MAMBA container and only 5 days exposure without cold transport) and 4 centrifuge 10g without constrains control..

Transcription profiling of Arabidopsis wild type and TROL (AT4G01050) knock-out plants

Project description:Here we describe TROL (thylakoid rhodanese-like protein), a nuclear-encoded component of thylakoid membranes that is required for sustaining efficient linear electron flow in vascular plants. Thus, TROL might represent a missing thylakoid membrane linker for the assembly of a ternary complex between FNR, ferredoxin and NADP+. Such a complex is necessary for maintaining photosynthetic redox poise and balancing between several alternative electron-transport pathways of oxygenic photosynthesis. TROL inactivation modulates the expression of 638 nuclear genes, revealing a novel retrograde signaling pathway. Chloroplasts are the major source of NADPH which is exported to the cytosol where it participates in various redox-dependent processes. TROL is most likely the first element in a metabolic signaling pathway which influences the expression of a large set of stress related genes. Among them are O-methyltransferases and anthocyanin 5-aromatic acyltransferase which are highly upregulated. Microarray analysis was performed in order to identify metabolic networks and pathways regulated by the deficient protein TROL. Comparing ATH1 Affymetrix data results, 317 genes were down-regulated and 321 genes were classified as up-regulated, amongst which mostly affected enzymes were catalyses, oxigenases, monooxygenases and reductases involved in the process of photosynthesis.

Transcription profiling of EDS1- and SA-dependent genes in nudt7-1

Project description:nudt7-1 mutant plant exhibit stunted growth, enhanced basal resistance, elevated SA levels and spontaneous leaf cell death that is restricted to single cells but does not spread. All of these phenotypes depend on EDS1, a key regulator of plant innate immunity. Moreover, SA depletion in nudt7-1 results in EDS1-dependent cell death exacerbation and strong growth retardation. In this this experiment, we used 4-week-old soil-grown plants to seek for EDS1- and SA-regulated genes in nudt7-1 to identify novel components of the EDS1- and SA-signalling pathways.

Project description:Seven temperature sensitive Saccharomyces cerevisiae BY4741 mutants (rsc3-1, abf1-101, reb1-212, rap1-1, mcm1, tbf1 and cep3-1) were grown at restrictive temperatures until a difference in OD600 was observed relative to a wild-type control. Nucleosomal DNA, whole genomic DNA and total RNA were isolated and hybridized onto yeast whole-genome tiling arrays.
