Transcription profiling of Arabidopsis leaf gene expression after growth under low light and low CO2

ABSTRACT: Internal sugar and light specific dependent regulation of leaf gene expression was addressed by changing [CO2] to lower than compensation point [CO2] in combination with light or prolonged darkness. Plants were grown on soil in a 12/12 h light/dark rhythm at 20Â°C day and night and under normal [CO2]. 5 weeks after germination, the above-ground rosettes of the non-flowering plants were harvested, 12 plants per sample. Plants were harvested 4hrs after the end of night (i) under low (< 50 ppm) [CO2] and 150 ÂµE fluorescent light , (ii) under normal [CO2] and light, and, (iii) under low [CO2] and prolonged darkness. The low [CO2] treatment started 30 min before the end of night and stopped with harvesting. Experiment Overall Design: 2 biological replicates of plants under 3 treatments (4hrs low CO2+light, 4hrs low CO2+prolonged darkness, and 4hrs normal CO2+light).

Transcription profiling of diurnal gene expression in Arabidopsis thaliana Col-0 rosette leaves

Project description:How do the transcript levels of leaf-expressed genes change in a normal day-night cycle? The interest is in genes that are regulated by the circadian clock and the diurnal component (i.e. light, metabolite changes). Plants were grown on soil in a 12/12 h light/dark rythm at 20Â°C day and night. 5 weeks after germination the rosettes of the non-flowering plants were harvested, 15 plants per sample. Plants were harvested at 6 timepoints every 4 hours beginning with the end of the night (still in darkness).

oxi1 transcriptome-Transcriptomic analysis on the effect of oxi1 mutation under high light.

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.

Hypometabolism to survive the long polar night in the diatom Fragilariopsis cylindrus

Project description:Diatoms, the major eukaryotic phytoplankton in polar regions, are essential to sustain food webs. As such, it is fundamental to understand the physiological mechanisms and associated molecular basis of resilience to polar night of diatoms. Here, we report an integrative approach that reveals that in prolonged darkness, the cell enters a state of hypometabolism associated with reduced transcriptional activity during which no cell division occurs. Minimal energy is provided by respiration via alternative oxidase and progressive degradation of protein, carbohydrate and lipid stores. We also report internal structural changes that manifest the morphological acclimation of cells to darkness. Our results further indicate that immediately after returning to light, the majority of cells were able to use photoprotective mechanisms and resume photosynthesis. Divisions of surviving cells resumed at rates similar to those before darkness. Our study demonstrates the robustness of this species to prolonged darkness at low temperatures.

Expression data provoked by H2O2 from plastid or peroxisomal origin

Project description:Reactive oxygen species (ROS) are key signalling molecules that regulate growth and development and coordinate responses to biotic and abiotic stresses. ROS homeostasis is controlled through a complex network of ROS production and scavenging enzymes. Recently, the first genes involved in ROS perception and signal transduction have been identified and, currently, we are facing the challenge to uncover the other players within the ROS regulatory gene network. The specificity of ensuing cellular responses depends on the type of ROS and their subcellular production sites. Various experimental systems, including catalase-deficient plants, in combination with genome-wide expression studies demonstrated that increased hydrogen peroxide (H2O2) levels significantly affect the transcriptome of plants and are capable of launching both defence responses and cell death events. We used microarrays to assess differential gene expression provoked by H2O2 from plastid or peroxisomal origin, respectively. Columbia-0 (Col-0, wild type), catalase-deficient Salk plants (10-15% of wild-type catalase activity; cat2-2; N576998; (Queval et al., 2007)) and A. thaliana plants expressing glycolate oxidase in chloroplasts (GO5 plants; (Fahnenstich et al., 2008)) were grown in soil under a 16h light/8h dark regime at photosynthetically active photon flux densities (PPFD) of 75 µmol quanta m-2 s-1 at 22°C day/18°C night temperatures and a CO2 concentration of 3,000 ppm. After three weeks of growth, plants were transferred to ambient CO2 concentration (380 ppm) and the same PPFD. Whole rosettes were harvested at 0h and 8h after transfer. Control samples were harvested at 8 h from plants continuously maintained in high CO2.

Acute effects of light on alternative splicing in light-grown plants

Project description:We report the results of a genome-wide analysis of AS in Arabidopsis thaliana plants exposed to a 2h light pulse given in the middle of the night, a treatment that simulates the effects of early dawn or late dusk signals. This light affects the plant transcriptome at multiple regulatory layers, and that light regulation of mRNA levels of splicing regulatory factors is likely to mediate light effects on AS contributing to adjust plant physiological processes to the prevailing light environment. Arabidopsis seedlings of the Columbia ecotype were grown under 12 hr light/12 hr dark cycles for 9 days. On the 10th day, half of the plants were exposed to a two-hour pulse of white light given in the middle of the night (ZT18), while the other half were kept in darkness as controls. Both groups of plants were harvested at ZT 20 and light effects on mRNA levels and AS were analyzed through RNA-seq.
