Project description:In order to elucidate the role of the Arabidopsis thaliana LLM-domain B-GATAs in response to high light intensities, a transcriptomic analysis of Col-0, a hexuple LLM-domain B-GATA mutant hex (gnc gnl gata15 gata16 gata17 gata17l) and GNLox under high-ligh stress conditions was performed.

Project description:cea13-01_oxi1 - oxi1 transcriptome - Transcriptomic analysis on the effect of oxi1 mutation under high light stress? - 5 weeks old mutannt (M) and wild type (WT) plants were exposed to high light and low temperature (1300-1350 µmol photons m-2s-1, 7°C/14°C day/night and 380ppm CO2) for 25 hours. ~100 mg fresh weight leaves were harvested, and total RNA prepared from them. For control experiments, leaves were harvested directly from the phytotron (No light stress). Three microarray comparisons were made: Mcontrol/WTcontrol, Mstress/WTstress and Mstress/Mcontrol . For each comparison, 2 biological replicates are performed. 6 dye-swap - genotype comparaison

Project description:Photoperiod is a circannual signal measured by biological systems to align growth and reproduction with the seasons. To understand the effect of photoperiod of gene expression in Arabidopsis thaliana in the absence of exogenous sugar under constant light intensity, we performed time course mRNA-seq analysis on 13-day old seedlings across three photoperiods with triplicates to identify photoperiod-regulated genes.

Project description:In bacteria, the biosynthesis of cysteine is accomplished by two enzymes that are encoged by the cysK and cysM genes. CysM is also able to incorporate thiosulfate to produce S-sulfocysteine. In plant cells, the biosynthesis of cysteine occurs in the cytosol, mitochondria and chloroplasts. Chloroplasts contain two O-acetylserine(thiol)lyase homologs, which are encoded by the OAS-B and CS26 genes. An in vitro enzymatic analysis of the recombinant CS26 protein demonstrated that this isoform possesses S-sulfocysteine synthase activity and lacks O-acetylserine(thiol)lyase activity. In vivo functional analysis of this enzyme in knockout mutants demonstrated that mutation of cs26 suppressed the S-sulfocysteine synthase activity that was detected in wild type; furthermore, the mutants exhibited a growth phenotype, but penetrance depended on the light regime. The cs26 mutant plants also had reductions in chlorophyll content and photosynthetic activity (neither of which were observed in oas-b mutants), as well as elevated glutathione levels. However, cs26 leaves were not able to properly detoxify ROS, which accumulated to high levels under long-day growth conditions. The transcriptional profile of the cs26 mutant revealed that the mutation had a pleiotropic effect on many cellular and metabolic processes. Our finding reveals that S-sulfocysteine and the activity of S-sulfocysteine synthase play an important role in chloroplast function and are essential for light-dependent redox regulation within the chloroplast. Using the Affymetrix ATH1 GeneChips, we performed a comparative transcriptomic analysis on leaves of the cs26 and wild type plants under two different photoperiod conditions. Wild type and cs26 mutant plants were grown on soil under a long-day photoperiod (LD) or under a short-day photoperiod (SD). Total RNA was extracted from the leaves of 3-week-old plants grown under identical LD conditions, and from the leaves of 5-week-old plants grown under identical SD conditions. Three biological replicates were performed for each sample and hybridized to the chips. We made two different comparisons to classify the differently expressed genes in the mutant plant: cs26 leaves under LD versus wild-type leaves under LD and cs26 leaves under SD versus wild-type leaves under SD.
