Sunlight provides energy for photosynthesis and is essential for nearly all life on earth. However, too much or too little light or rapidly fluctuating light conditions cause stress to plants. Rapid changes in the amount of light are perceived as a change in the reduced/oxidized (redox) state of photosynthetic electron transport components in chloroplasts. However, how this generates a signal that is relayed to changes in nuclear gene expression is not well understood. We modified redox state in ...[more]

Light effect on the hormonal and transcriptional status of winter and spring wheat plants during cold hardening

Project description:The effect of light during the development of freezing tolerance was studied in winter wheat (Triticum aestivum L. var. Mv Emese) and spring wheat variety Nadro. Ten-day-old plants were cold hardened at 5°C for 12 days either under normal (250 mmol m-2 s-1) or low light (20 mmol m-2 s-1) conditions. Samples of Emese (E) and Nadro (N) plants grown at 18°C under normal (NL) and low (LL) light fluences were compared to each other in a simple loop design and E-NL vs. E-LL; N-NL vs. N-LL; E-NL vs. NLL and E-LL vs. N-LL comparisons were made.

Transcription profiling of Arabidopsis seedlings grown under thermocycles and/or photocycles or continuous conditions

Project description:In most organisms biological processes are partitioned, or phased to specific times over the day through interactions between external cycles of temperature (thermocycles) and light (photocycles), and the endogenous circadian clock. This orchestration of biological activities is achieved in part through an underlying transcriptional network. To understand how thermocycles, photocycles and the circadian clock interact to control time of day specific transcript abundance in Arabidopsis thaliana, we conducted four diurnal and three circadian two-day time courses using Affymetrix GeneChips (ATH1). All time courses were carried out with seven-day-old seedlings grown on agar plates under thermocycles (HC, hot/cold) and/or photocycles (LD, light/dark), or continuous conditions (LL, continuous light; DD, continuous dark, HH, continuous hot). Whole seedlings (50-100), including roots, stems and leaves were collected every four hours and frozen in liquid nitrogen. The four time courses interrogating the interaction between thermocycles, photocycles and the circadian clock were carried out as two four-day time courses. Four-day time courses were divided into two days under diurnal conditions, and two days under circadian conditions of continuous light and temperature. Thermocycles of 12 hours at 22C (hot) and 12 hours at 12C (cold) were used in this study. The two time courses interrogating photoperiod were conducted under short days (8 hrs light and 16 hrs dark) or long days (16 hrs light and 8 hrs dark) under constant temperature. In addition, the photoperiod time courses were in the Landsberg erecta (ler) accession, in contrast to the other time courses that are in the Columbia (col) background. The final time course interrogated circadian rhythmicity in seedlings grown completely in the dark (etiolated). Dark grown seedlings were synchronized with thermocycles, and plants were sampled under the circadian conditions of continuous dark and temperature.

Circadian expression data of Synechococcus in WT, rpoD6-null, sasA-null and rpaA-null strains

Project description:In the unicellular cyanobacterium, Synechococcus elongatus PCC 7942, most genes show rhythmic expression controlled by the Kai-based clock under continuous light conditions (LL). We found that rpoD6-null mutants impaired expression of clock-controlled genes peaking at hours 8-10 in LL, while sasA-null or rpaA-null mutants each arrested the expression profiles at subjective dawn. Time-course data (0-24 h) of wild type (WT), rpoD6-null, sasA-null and rpaA-null S. elongatus PCC 7942 strains analyzed under continuous light (LL) conditions after two 12h:12h light:dark (LD) cycles using Affymetrix high-density oligonucleotide microarrays (GeneChip CustomExpress Arrays) representing 2,515 predicted protein-coding genes on the genome of Synechococcus elongatus PCC 6301, which can be used also for the almost homologous strain, S. elongatus PCC 7942.

Comparative analysis of gene expression in response to LL-37 treatment

Project description:To identify the potential LL-37-responsed genes, we treated cells with or without LL-37 and their correspondent transcriptional profiles were compared. Total 104 significant genes were identified. Among them, 70 genes are upregulated in repsonse to LL-37 while 34 genes are downregulated in comparison with the control cells. LL-37 responsed gene was measured after 3 h growth in YPD followed by 30 min of incubation in the presence of 5 ug/ml LL-37 in RPMI. Two batches of five independent experiments were performed.

Impact of light and thioredoxins on the landscape of the plant thiol-disulfide proteome

Project description:Thiol-based redox regulation is a crucial post-translational mechanism to acclimate plants to changing light availability. Here, we conduct a biotin-switch-based redox proteomics study to systematically investigate dynamics of the thiol-redox network in response to temporal changes in light availability and across genotypes lacking parts of the NTRC/thioredoxin (Trx) systems in the chloroplast. Temporal dynamics revealed light leading to marked decreases in the oxidation states of 75 chloroplast proteins mainly involved in photosynthesis during the first 10 min, followed by their partial re-oxidation after 2-6 hours into the photoperiod. This involved f, m and x-type Trx proteins showing similar light-induced reduction-oxidation dynamics, while NTRC, 2-Cys-Prx and Trx y2 showed an opposing pattern, being more oxidized in the light, compared to the dark. In Arabidopsis trxf1f2, trxm1m2 or ntrc mutants, most protein candidates showed increased oxidation states, compared to the wild type, suggesting their light-dependent dynamics to be related to the NTRC/Trx network. In this context, deficiencies in f- and m-type Trxs were found to have different impacts on the thiol-redox proteome depending on the light environment, being higher in constant and fluctuating light, respectively, while NTRC deficiency having a strong influence in all light conditions. Results indicate the plant redox proteome to be subject to dynamic changes in reductive and oxidative pathways to cooperatively fine-tune photosynthetic and metabolic processes in the light. This involves f-type Trxs and NTRC to play a role in constant light conditions, while both m-type Trxs and NTRC being important to balance changes in protein redox-pattern during dynamic alterations in fluctuating light intensities.

Response of Synechococcus sp. WH7803 LL- and and HL- acclimated cells to oxidative stress (HP and MV)

Project description:To identify the respective roles of light and ROS in the photoinhibition process and detect a possible light-driven tolerance to oxidative stress, we compared the transcriptomic responses of Synechococcus sp. WH7803 acclimated to low (LL) or high light (HL) to oxidative stress, induced by hydrogen peroxide (H202) or methylviologen (MV). Cultures were acclimated during many generations to continuous low light (LL, 18 ?mol photons m-2 s-1, hereafter LL cells) and high light (HL, 250 ?mol photons m-2 s-1, hereafter HL cells) provided by Sylvania Daylight 58W/154 fluorescent bulbs. For all stress experiments performed in this study, exponentially growing cultures (1 to 3 x 107 cells mL-1), were split into subcultures and submitted to oxidative stress by addition of H2O2 or MV and harvested when PSII quantum yield fell to half of the initial value. For H2O2 experiments, this level of PSII photoinactivation was reached 2 h after submitting LL and HL cultures to 750 M and 25 M respectively. Because of the large divergence in dose and kinetics responses to MV between LL- and HL cells, it was not possible to find MV concentrations leading to 50 % decrease of quantum yield at the same time for both light acclimations. Thus, array analyses for MV were performed on HL and LL cultures incubated at the same MV concentration (50 M) but harvested once PSII quantum yield was halved, i.e. after 1 and 3.5 h of stress respectively. All hybridizations were performed on 4 independent biological replicates and using as reference sample a pool of RNA from all samples investigated in this study. Pairwise comparison were performed to analyze the stress induced by either H2O2 or MV on both LL- and HL cultures (i.e. LL-Ct vs. LL+MV, LL-Ct vs. LL+H2O2, HL-Ct vs. HL+MV, HL-Ct vs. HL+H2O2) as well as to compare the steady state acclimation to different light conditions (i.e. LL-Ct vs. HL-Ct).
