Photooxidative stress and light acclimation in the PSII antenna-deficient ch1 mutant

ABSTRACT: cea10-02_light - photooxidative stress - To characterize the metabolic pathways implicated in oxidative stress responses and in acclimation mechanisms in the ch1 mutant - The extracts are carried out starting from sheets of Arabidopis thaliana having pushed on compost in controlled conditions (light: 250 µmol.m-2.s-1, temperature: 22°C day 18°C night, moisture: 55%, photoperiod: 8:00 jour/16h night) during 4 and 8 weeks for respectively the Col0 genotype and the mutant ch1. The acclimatization of the plants is done during 48 H under an average luminous intensity (450 µmol.m-2.s-1, photoperiod 8:00), whereas the stress requires a strong luminous intensity (900 µmol.m-2.s-1, photoperiod 8:00) and low temperature (10°C day, 14°C night) also during 48 hours. 24 dye-swap - genotype comparison, treated vs untreated comparison

Interactions between H2O2 and glutathione in gene expression

Project description:rs08-03_glutathion - glutathion - How does glutathione content or reduction state affect H2O2-induced changes in the transcriptome? - Three single Arabidopsis mutants were used: cat2, knockout for catalase2 and so enriched in H2O2; cad2, defective in glutathione content; cytGR, knockout for cytosolic glutathione reductase. Cat2 was crossed with cad2 and cyt GR, and col0, 3 single mutants, and 2 double mutants were sampled in controlled growth conditions either in 8h or 16h photoperiod.

Differential expression in laccase mutants of Arabidopsis thaliana

Project description:ra10-01_laccases; laccase mutations. We demonstrated that laccases are involved in lignin polymerisation. Mutants have already been tested on microarrays and there is few differences compared to wild-type. The laccase mutation seems surgical. We possess a new double mutant, called snips, with a semi-dwarf phenotype, and we want to determine its profile. Each mutant was compared to wild type. All plants were harvested at the same developmental stage in the same growth chamber between 10h30 and 11h. 10 dye-swaps. CATMA arrays.
