Project description:We have identified a gene encoding a polycomb-chromo domain binding protein. Complete knockout of these plants do not lead to a phenotype, but a reduction of gene expression in RNAi line produces a defined phenotype. This argues in favour of a compensation mechanism that is switched on once the concentration of the gene reaches a control level.The aim of the experiment is to search for such compensatory factors that are up-regulated in the knockout line.

Project description:The aim is to study the function of peroxisomal NAD-malate dehydrogenase in fatty acid beta-oxidation, glyoxylate cycle and photorespiration. Both peroxisomal MDH genes (At2g22780 and At5g09660) have been knocked out with T-DNA insertions and a double mutant made. Double mutant seedlings are blocked in beta-oxidation - they are 2,4DB resistant and beta-oxidation genes are repressed. They carry out glyoxylate cycle as normal. Plants grow well in soil and produce seed. Microarray analysis will tell us the extent of changes in gene expression in the mutant. For microarray analysis seeds are stratified at 4 C on agar medium with 1/2 strength M&S salts and 1% sucrose for 2 days, then seedlings grown for 2 days at 20 C in the light (100 umol/m2/s). Triplicate samples will be grown for mutant and wild type (col-0) and RNA isolated from each.

Project description:In this experiment we tested the transcriptome of transgenic Arabidopsis seedlings (5-day-old) constitutively expressing the zinc-finger protein Zat12 (At5g59820) under the control of the 35S-CaMV promoter (Zat12). The transcriptome of these seedlings was compared to that of wild type seedlings grown under the same conditions (WT) and to that of wild type seedlings grown under the same conditions and subjected to a hydrogen peroxide stress (WT+H2O2). Hydrogen peroxide treatment was performed by applying 20 mM hydrogen peroxide for 1 hour. In parallel to these experiments transgenic plants expressing Zat12 were subjected to a similar hydrogen peroxide stress (Zat12+H2O2). All treatments were performed with similar size and age seedlings grown in liquid culture (MS) and sampled at the same time as described by Davletova et al., 2005.

Project description:The Arabidopsis transcription factor WRKY27 was found to be involved in plant defense towards Ralstonia solanacearum GMI1000. To identify target genes of WRKY27, we introduced a functional tagged version of WRKY27 into two independent Arabidopsis wrky27 knockout lines (ecotype Columbia) under the control of the estrogen receptor-based chemical-inducible system. 18 days old plants grown on soil (Metro Mix 200) at 22oC under a 10/14 h light/dark cycle were treated for 6h with 10 microM beta-estradiol after which RNA was immediately isolated. The two independent knockout lines transformed with the empty vectors (pMD::XVE-SALK and pMD::XVE-ETL) served as controls and were grown under the same conditions and treated identically as the experimental plants.

Project description:Arabidopsis has two genes, Arabidillo-1 and -2, related to animal Armadillo/ beta-catenin (Coates, 2003). Armadillo/beta-catenin directly activates the expression of developmental and cell proliferation genes, and also independently regulates cell-cell adhesion. Arabidillo proteins are nuclear and promote lateral root development. We aim to identify candidate Arabidillo target genes by comparing the transcriptomes of wild type, arabidillo-1/2 mutant and Arabidillo-1 overexpressing lines. The experiment will compare Col-0 (3 slides) with a 35S::Arabidillo-1-YFP overexpressing line (3 slides) and Col-3 with the arabidillo-1/2 mutant (3 slides). Each RNA prep will be from plate-grown 7-day old seedlings. Reference: Coates, JC (2003) Armadillo repeat proteins: beyond the animal kingdom?

Project description:Calcium has been shown to be an important signalling molecule in the transduction of abiotic stress signals in Arabidopsis thaliana. Alteration of the calcium signature through the use of inhibitors has been shown to result in changes in the expression of certain downstream abiotic stress-induced genes. However, the communication of this signal through specific calcium-sensitive intermediate molecules has remained poorly elucidated. Various candidate molecules exist and including calcinurin, calcium-dependent protein kinases and calmodulin. Recently, a screen of an Arabidopsis thaliana cDNA expression library with calmodulin resulted in the isolation of the protein designated calmodulin-binding transcriptional activator or AtCAMTA that may function as one of these calcium-sensitive intermediate molecules. The Arabidopsis genome contains six CAMTA genes (AtCAMTA1-6), all of which are expressed in varying tissues throughout development. AtCAMTA1 was shown to function as a transcriptional activator through the expression of a chimeric protein consisting of the bacteria LexA protein fused to various segments of AtCAMTA expressed in yeast. In order to identify putative target genes of AtCAMTA1 in Arabidopsis we plan to analyse the transcriptome of AtCAMTA1 loss-of-function mutants. The gene expression pattern of two previously characterised alleles of AtCAMTA1 will be compared to wild type.
