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: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: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.

Project description:Nontargeted and targeted metabolomics measurements of abiotic stress responses in three-week-old Arabidopsis thaliana plants' rosette leaf tissue for Col-0 wild type plants and double/triple knockout mutants of aquaporins (pip2;1 pip2;2 and pip2;1 pip2;2 pip2;4) treated with drought, heat at different air humidities, or combined drought-heat stress at different air humidities. This experiment contains FT-ICR-MS measurements for 103 Arabidopsis thaliana rosette leaf samples covering three genotypes under six different environmental conditions. The three genotypes comprise the Col-0 wildtype and two loss-of-function mutants of aquaporins, a pip2;1 pip2;2 double mutant and a pip2;1 pip2;2 pip2;4 triple mutant (respective AGI locus identifiers: AT3G53420, AT2G37170, AT5G60660). The six conditions include control condition (well-watered, 22 °C, 70% relative air humidity), drought stress (one week without watering), heat stress without changing the absolute humidity of the ambient air (6 hours at 33 °C, 37% relative air humidity), heat stress with supplemented air humidity to maintain a constant vapor pressure deficit before and during the heat episode (6 hours at 33 °C, 84% relative air humidity), and the combinations of drought pretreatment with each of the two heat stress variants (one week of drought followed by 6 hours of heat stress). Samples from all conditions were harvested at the same time (within 15 min starting at 5 pm). For validation, GC-TOF-MS measurements were done for two genotypes (wildtype, double mutant) and two conditions (drought, control) on partially overlapping samples.
