Project description:Transcriptional profiling of genes regulated by PaWRKY1 transcription factor A PaWRKY transcription factor from orchid plants is expressed in Arabidopsis, and the PaWRKY-regulated genes are studied Comparison of empty-vector control and transgenic 35S-PaWRKY1 Arabidopsis Affymetrix GeneChip assay were performed by the Affymetrix Gene Expression Service Lab (http://ipmb.sinica.edu.tw/affy/), supported by Academia Sinica, Taiwan
Project description:Constitutive expression of VvMYBPAR in Arabidopsis was found to accumulate proanthocyanidins when the plants were grown on sucrose-supplemented media to induce anthocyanins. To identify the putative targets of VvMYBPAR, the transcriptome analysis of the transgenic lines which highly express VvMYBPAR was carried out using NimbleGen microarray. Three transgenic lines in which VvMYBPAR were constitutively expressed under the control of 35S promoter vs. empty vector transformants were compared.
Project description:To identify the genes regulated by Arabidopsis ERF19. 35S::ERF19 transgenic Arabidopsis was created, them we employ whole genome microarray expression profiling as a discovery platform to identify genes with the potential to regulae by ERF19. The RNA was isopated from the whole flower of control and 35S::ERF19 transgenic Arabidopsis.
Project description:We performed immunoprecipitation analysis with leaves from 35S::NusG:MYC transgenic lines throung the MYCantibody, and the product was subjected to LC-MS analysis.
Project description:DNA methylation is an important epigenetic modification involved in many biological processes, and active DNA demethylation plays critical roles in regulating expression of genes and anti-silencing of transgenes. In this study, we isolated mutations in one arabidopsis gene, ROS5, which causes the silencing of transgenic 35S-NPTII because of DNA hypermethylation, but no effect on transgenic RD29A-LUC. ROS5 encodes an atypical small heat shock protein. ROS5 can physically interact with IDM1 and is required for preventing DNA hypermethylation of some endogenous genes that are also regualated by IDM1 and ROS1. We propose that ROS5 may regulate active DNA demethylation by interacting with IDM1, thereby creating a friendly chromatin environment that facilitates the binding of ROS1 to erase DNA methylation.
Project description:au13-08_atpplaii-alpha - transcriptional profilling of arabidopsis plants. Understanding the physiological role of pPLAIIα; under control and drought stress conditions. Study on empty vector, overexpressor and antisense A. thaliana lines.
Project description:To search for regulators of DMC1 stability, we generated DMC1-FLAG transgenic Arabidopsis plants and conducted immunoprecipitation-mass spectrometry (IP-MS) assay. 6,477 peptides corresponding to 2309 proteins were identified and 1009 proteins remained after removing background interactions using plants transformed with the corresponding empty vector (FLAG). GO term analysis was performed with the obtained data and revealed that ubiquitin proteasome pathway components are significantly enriched among the candidate proteins.
Project description:We performed transcriptome and ribosome immunoprecipitation studies of transgenic Arabidopsis (Arabidopsis thaliana) Columbia seeds expressing a His6FLAG-tagged version of the ribosomal large subunit protein L18B (35S:HF-RPL18B)
