Project description:Arabidopsis thaliana plants are grown for one week in a hydroponic growth system and transferred to new plant medium containing low levels of Caesium-137 (control is transferred to new medium with no radioactivity) and left for further two weeks. Levels of Caesium-137 are chosen according to research and are reflecting occurring levels found in radioactive contaminated soil. The plants are then harvested and the samples divided into shoot and root samples.

Project description:Purpose: Analyze changes in the transcriptome of Arabidopsis thaliana in response to chronic exposure to silver nitrate at 4 μg/mL concentration. Methods: mRNA was extracted from non-treated and silver nitrate-treated 14-day old Arabidopsis thaliana seedlings using the RNAeasy extraction kit (Qiagen). RNA-seq libraries (3 rep/treatment and 3 reps/control) constructed with the TruSeq Stranded mRNA Sample Preparation kit (Illumina) were paired-end sequenced (100-nt read length) on an Illumina Nova Seq6000 system. Reads were mapped to the A. thaliana TAIR10 reference genome sequence and transcript levels were analyzed using the softare CLC Genomics Workbench (version 20.0.4, Qiagen). Results: Chronic exposure of A. thaliana plants to silver nitrate caused a change in the abundance of transcripts: AT2G01520 and AT4G12550, but no measureable impact on the rest of the transcriptome. Conclusions: Exposure of A. thaliana to silver nitrate at 4 μg/mL has minor impact on the transcriptome.

Project description:VC133+137, DNA methylation in ddm1 seedling Arabidopsis thaliana plants

Project description:Arabidopsis thaliana is a well-established model system for the analysis of the basic physiological and metabolic pathways of plants. The presented model is a new semi-quantitative mathematical model of the metabolism of Arabidopsis thaliana. The Petri net formalism was used to express the complex reaction system in a mathematically unique manner. To verify the model for correctness and consistency concepts of network decomposition and network reduction such as transition invariants, common transition pairs, and invariant transition pairs were applied. Based on recent knowledge from literature, including the Calvin cycle, glycolysis and citric acid cycle, glyoxylate cycle, urea cycle, sucrose synthesis, and the starch metabolism, the core metabolism of Arabidopsis thaliana was formulated. Each reaction (transition) is experimentally proven. The complete Petri net model consists of 134 metabolites, represented by places, and 243 reactions, represented by transitions. Places and transitions are connected via 572 edges.

Project description:Purpose: Analyze changes in the transcriptome of Arabidopsis thaliana in response to sublethal concentrations of silver nanoparticles in order to gain insight into phytotoxicity caused by these nanomaterials. Methods: mRNA was extracted from non-treated and silver nanoparticle-treated 14-day old Arabidopsis thaliana seedlings using the RNAeasy extraction kit (Qiagen). RNA-seq libraries (3 rep/treatment and 3 reps/control) constructed with the TruSeq Stranded mRNA Sample Preparation kit (Illumina) were single-end sequenced (100-nt read length) on an Illumina HiSeq2500 system. Reads were mapped to the A. thaliana TAIR10 reference genome sequence and transcript levels were analyzed using the softare CLC Genomics Workbench (version 7.0.40, Qiagen). Results: Chronic exposure of A. thaliana plants to silver nanoparticles caused a change in abundance of transcripts involved in cell wall synhtesis and response to oxidative and biotic stress-related genes. Conclusions: While exposure to silver nanoparticle lead to gene expression changes, the reduction in chlorophyll concentration and carbon assimilation rate measured in exposed plants cannot be attributed to a shift in photosynthesis-related gene regulation.

Project description:To identify genes of the guard cell transcriptome of Arabidopsis thaliana enriched guard cell samples were compared with total leaf tissue. Genes of the abscisic acid and humidity response of Arabidopsis thaliana guard cells were identified by treatment with ABA-Spray and low humidity.

Project description:Formaldehyde is a toxic volatile organic compound and its mechanism of toxicity to plant has not yet been revealed. This experiment was designed to identify formaldehyde-responsible genes under exposure to low or high concentration of airborne formaldehyde for a short period of time. 7-weeks old Arabidopsis thaliana wild type (ecotype: Columbia) plants were exposed to gaseous formaldehyde at 1-2 ppm (low), 14-16 ppm (high), or less than 0.04 ppm (air control) at 24oC under light-condition for 150 minutes inside a chamber for formaldehyde exposure. Total RNA was isolated from rosette leaves of exposed plants and was applied to microarray analysis. We investigated into formaldehyde dose response on gene expression of Arabidopsis and tried to understand the toxic mechanisms of formaldehyde using an Affymetrix Arabidopsis genome array ATH-1.
