Project description:Proteins from plant shoot and root tissues were extracted from wild-type Arabidopsis thaliana ecotype Columbia (Col-0). They were enriched on conditioned U(VI)-loaded and U(VI)-free Duolite C467 beads. The enriched proteins were identified and quantified by label-free shotgun proteomics.
Project description:Proteomic Analysis of the total proteome from Arabidopsis thaliana SUMO E3 Ligase mutants siz1-2 and mms21-1 and wild-type (Col-0) 8-day old seedlings
Project description:We have used a strain of Tobacco etch potyvirus (TEV) experimentally adapted to Arabidopsis thaliana ecotype Ler-0 to infect a set of seven A. thaliana plant ecotypes(Col-0, Ei-2, Wt-1, ler-0, Oy-0, St-0). Each ecotype was inoculated with the same amount of the virus. Using commercial microarrays containing probes Arabidopsis thaliana ssp. Col-0 plant transcripts, we explored the effect of viral infection in the plant transcriptome

Project description:Macrophomina phaseolina (Mp) is a soil-borne pathogenic fungus known to infect more than 500 plants species including important crops. Here we report the use of a novel agar plate-based pathosystem using the model plant Arabidopsis thaliana (Arabidopsis) to study plant defense reponses to Mp, specifically a comparison between wild type Col-0 and double mutant ein2/jar1 roots with and without Mp infection, at two time points, by RNA-seq.
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 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.
