Transcriptional charecterization of the eds4 mutant transcriptome
Ontology highlight
ABSTRACT: The aim of this study was to perform a transcriptional characterization of the Arabidopsis eds4 mutant. To this end two separate experiments were performed: Experiment 1: comparison of the transcriptional profile (RNA-seq) of eds4 Arabidopsis mutants in contrast to wild type Col-0 accession grown under continuous light conditions. Experiment 2: Analysis of the distribution of transcripts (RNA-seq) between nucleus and cytoplasm in the eds4 Arabidopsis mutants in comparison to wild type Col-0 plants grown under continuous light conditions.
Project description:Transcriptional profiling of Arabidopsis dark-induced senescence comparing wild type (Col-0) with pif quadruple (pif1/3/4/5) mutant. After synchronized germination, the plants were grown under continuous white light for 7 days and transferred to darkness for 2 days to induce senescence. Goal was to determine the effect of PIFs on transcriptomic regulation during dark-induced senescence.
Project description:Wild type Arabidopsis Col-0 plants and mutants depleted of the catalytic subunit of the ribosome-associated N-acetyltransferase A (NatA) complex (amiNAA10) were grown on soil for six weeks under short-day conditions (8h light, light intensity: 100 µE, 21 °C/18 °C temperature (day/night), 50 % humidity). Proteasome and deubiquitinase activity were inhibited at 10 am (2 h of light) by floating leaf discs on ½ Hoagland supplemented with 50 µM MG132 and 20 µM PR-619 for 5 h.
Project description:The aim of this study was to analyze the impact of autotetraploidy on gene expression in Arabidopsis thaliana by comparing diploid versus tetraploid transcriptomes. In particular, this included the comparison of the transcriptome of different tetraploid A. thaliana ecotypes (Col-0 vs. Ler-0). The study was extended to address further aspects. One was the comparison of the transcriptomes in subsequent generations. This intended to obtain information on the genome wide stability of autotetraploid gene expression. Another line of work compared the transcriptomes of different diploid vs. tetraploid tissues. This aimed to investigate whether particular gene groups are specifically affected during the development of A. thaliana autotetraploids. Samples 1-8: Arabidopsis thaliana Col-0 tetraploid transcriptome. Transcriptional profiling and comparison of diploid vs. tetraploid Col-0 seedlings. The experiment was carried out with pedigree of independently generated and assessed tetraploid Col-0 lines. Samples 9-12: Arabidopsis thaliana Ler-0 tetraploid transcriptome. Transcriptional profiling and comparison of diploid vs. tetraploid Ler-0 seedlings. The experiment was carried out with pedigree of independently generated and assessed tetraploid Ler-0 lines. Samples 13-24: Arabidopsis thaliana Col-0 tetraploid transcriptome. Transcriptional profiling and comparison of diploid vs. tetraploid Col-0 leaves (6th - 8th). The experiment was carried out with pedigree of independently generated and assessed tetraploid Col-0 lines. Samples 25-32: Arabidopsis thaliana Ler-0 tetraploid transcriptome. Transcriptional profiling and comparison of diploid vs. tetraploid Ler-0 leaves (6th - 8th). The experiment was carried out with pedigree of independently generated and assessed tetraploid Ler-0 lines. Samples 33-36: Arabidopsis thaliana Ler-0 tetraploid transcriptome. Transcriptional profiling and comparison of tetraploid vs. tetraploid Ler-0 seedlings from the second (F2) and third (F3) generation after induction, respectively. The experiment was carried out with pedigree of independently generated and assessed tetraploid Ler-0 lines. Samples 37-40: Arabidopsis thaliana Col-0 tetraploid transcriptome. Transcriptional profiling and comparison of tetraploid vs. tetraploid Col-0 seedlings from the second (F2) and third (F3) generation after induction, respectively. The experiment was carried out with pedigree of independently generated and assessed tetraploid Col-0 lines. Samples 41-44: Arabidopsis thaliana Col-0/Ler-0 diploid transcriptome. Transcriptional profiling and comparison of diploid Col-0 vs. diploid Ler-0 seedlings. The experiment was carried out with pedigree of esrablished lines. Samples 45-48: Arabidopsis thaliana Col-0/Ler-0 tetraploid transcriptome. Transcriptional profiling and comparison of tetraploid Col-0 vs tetraploid Ler-0 seedlings. The experiment was carried out with pedigree of independently generated and assessed tetraploid Col-0 and Ler-0 lines.
Project description:Wild type Arabidopsis Col-0 plants and mutants depleted of the catalytic subunit of the ribosome-associated N-acetyltransferase A (NatA) complex (amiNAA10) were grown on soil for six weeks under short-day conditions (8h light, light intensity: 100 µE, 21 °C/18 °C temperature (day/night), 50 % humidity). The translatome of both genotypes after 2 hours of light (10 am) was determined by feeding of the trackable Met-analogue azidohomoalanine for 4 hours to leaf disks floated on ½ Hoagland medium containing 50 µM azidohomoalanine in the light.

Project description:Transcriptional comparison of Arabidopsis thaliana pvip1;pvip2 RNAi double mutants against Col-0 wildtype. Tissue used: whole rosettes of 4-week-old plants grown under short-day conditions (8h light; 20oC). 3 biological replicates for each. Control = Col-0 and mutant = pvip1;pvip2. PVIP = Potyvirus-VPg-interacting protein (Dunoyer et al. 2004 J. Virol. 78: 2301-2309). 6 samples were used in this experiment.
