Project description:au08-04_dfo - analysis of deferoxamine treated leaves and roots - What are the effects of the siderophore deferoxamine on Arabidopsis leaves and roots? - Plants were allowed to grow for 5-6 weeks. The nutrient solution contains 0.25 mM Ca(NO3)2.4H2O, 1mM KH2PO4, 0.5 mM KNO3, 1mM MgSO4.7H2O, 50 µM H3BO3, 19 µM MnCl2.4H2O, 10 µM ZnCl2, 1 µM CuSO4.5H2O, 0.02 µM Na2MoO4.2H2O and 50 µM FeNa-EDTA. Plants were subjected to an 8 h light/16 h dark cycle, at 19°C, with 70% relative humidity. Leaves of six week old hydroponically grown A. thaliana Col0 plants were infiltrated with 1mM deferoxamine or sterile distilled water. Leaves were harvested 7 and 24 h.p.i.

Project description:Transcriptional profiling of fully developed leaves of Arabidopsis Col0 plants heat-stressed for 25 min at 27.7 degrees Celsius. Goal was to isolate and study the influence of temperature and vpd change in the 30 min high light-stress experiments, since the Isolight rises leaf temperature to 27.5C and increases the vpd from 5 min of exposure.

Project description:Purpose: Overexpression of VDE, ZEP and PsbS (VPZ) in plants confers enhanced dynamics of non-photochemical quenching of NPQ under FL light. VPZ overexpression in tobacco has been reported to increase plant biomass under fluctuating light. However, our work demonstrates that such strategy had no advantageous effect when asssayed in Arabidopsis thaliana. To investigate whether this observation is due to impairements in signaling pathways due to the expression of VPZ in Arabidopsis thaliana, transcriptome profiles of VPZ plants exposed to fluctuating light or high light were conducted. Methods: mRNA-Seq libraries were prepared from 21-d-old Col0 plants and VPZ lines #2 and #4 cultivated under standard control conditions and then exposed to fluctuating light or high light for 6h and 30 h. Standard Illumina protocols were used for mRNA-Seq sequencing. Triplicates for 3 independent plants were used. Adaptor sequences were removed with Trimmomatic and resulting reads mapped to the Arabidopsis genome (Araport11) with Tophat 2.1.1. Normalised counts reads were quantified with featureCounts to provide processed data files and differential expression analysis were conducted with the DEseq2 pipeline. Results: mRNA-Seq libraries contained app. 9 milion reads each. Transcript analysis for differential gene expression was conducted according to the Tophat/featureCounts/DESeq2 pipeline. To declare significant differences, a cut-off for absolute log2(FC) ≥ 1 compared to the initial timepoint (0h) and FDR ≤ 0.05 was applied. Significant transcripts exclusively found for Col0 and both VPZ lines in each time-point were considered for subsequent analysis. Accordingly, 528 and 415 transcripts (6h and 30h) were found for Col0, and 326 and 896 (6h and 30h) for the VPZ under control conditions. For FL, 490 and 591 transcripts qualified as specific (6h and 30h) for Col0 and 938 and 401 (6h and 30h) for VPZ. Strikingly, the amount of transcripts raised to 2847 and 2902 DEGs (6h and 30h) for Col0, whereas only 546 and 304 (6h and 30h) were detected for VPZ under HL. transcripts). Conclusions: the overexpression of VPZ in Arabidopsis leads to particular transcriptome response under fluctuating light related to changes in photosynthesis and response to abscisic acid, among all. However, Col0 displayed wider transcriptome responses than VPZ after exposure to high light .

Project description:Transcription factors ERF5 and ERF6 may play a regulatory role in regulating the expression of chitin-responsive genes. We compared the gene expression profiles between the double mutant erf5/6 and WT plants in response to chitooctaose using the Affymetrix Arabidopsis Whole Genome Arrays. Both the double mutant erf5/6 and WT plants were grown in liquid MS medium in a growth chamber with constant light. Two-week-old seedlings were treated with chitooctaose at a final concentration of 1 uM for 30 minutes. The controls were similarly treated with an equivalent amount of ddH2O. The treated seedlings were harvested for RNA isolation. Three biological replicates were conducted for the experiment.
