Project description:Comparison of Arabidopsis stem base to first internode transcriptional profiles

Project description:Stem samples of wildtype Columbia plants and the wox4-1 mutant (Gabi_462G01) were analyzed in order to draw a connection between general transcriptomic changes during interfascicular formation in the wildtype and WOX4-dependent gene regulation during this process. We used microarrays to identify factors downstream of WOX4 in the formation of the interfascicular cambium. Transcriptional profiling, comparing wildtype Columbia and wox4-1 plants. RNA was extracted from 3 biological replicates per plant line and sample type (stem base, first internode), each consisting of a pool of 13-17 stem samples.

Project description:Subsequently to primary growth, most dicotyledonous plants undergo secondary growth leading to an increased diameter of growth axes. During secondary growth initiation in shoots, a cylindrical meristem, the vascular cambium, is established by the initiation of meristematic activity in interfascicular regions, a process that ultimately leads to the formation of a continuous cylinder of vascular tissue along the shoot axis. In Arabidopsis this happens in a reduced area at the very base of the stem. In this study, a transcriptional comparison between the base and the first internode has been performed in order to asses the physiological state of both sample types and search for potential key regulators of the process. Total RNA was extracted from the base and the first internode from stems of 15cm tall Arabidopsis plants (ecotype Col-0). After RNA amplification, Cy3 or Cy5 targets were produced. Three independent biological replicates were used for each type of sample. Three hybridizations were performed, representing the three independent biological replicates, being one of them a dye swap.

Project description:To exlore more circRNAs involved in Arabidopsis thaliana, we deeply sequenced 14 samples including whole plants from four developmental stages (rosette leaves > 1 mm in length; rosette growth complete; 50% of flowers to be produced have opened; first silique shattered), aerial part of plants from four stress treatments (control, drought, salinity and heat), five organs (roots, stems, leaves, flowers and siliques) and a mixed sample from whole plants across the lifespan (cotyledons emergence, rosette leaves﹥1 mm, rosette growth complete, first flower open, flourishing florescence, first silique shattered, senescence). The total RNA was purified by rRNA-depletion and linear RNA removal with RNAseR, and paired-end (PE) sequenced by Illumina HiSeq 2500 (read length, PE125, the mixed sample) and Illumina Hiseq X Ten (read length, PE150, 13 independent samples) platforms. We obtained 181.97 Gb raw data (151.37 Gb from 13 samples and 30.6 Gb from a mixed sample) and identified 5861 circRNAs with expression quantity. We annotated the parent genes of these circRNAs and predicted their target sites of microRNAs.

Project description:The goal of this project is to compare the primary metabolite profile in different tissue types of the model plant Arabidopsis thaliana. Specifically, plants were grown hydroponically under the long-day (16hr light/day) condition at 21C. Tissue samples, including leaves, inflorescences, and roots were harvest 4 1/2 weeks post sowing. Untargeted primary metabolites profiling was carried out using GCTOF.

Project description:We report the application of laser capture microdissection (LCM) for high resolution transcriptome profiling of the second internode of the Arabidopsis thaliana inflorescence stem. In this series, we used LCM to determine and compare the transcriptome profiles of the phloem cap, the pith, and the remaining vascular bundle area.

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:To identify genes of the guard cell transkriptome 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. Ost1-2 and slac1-3 mutants were compared to their wildtype.
