Methotrexate treatment-dynamics of Arabidopsis transcriptome during folate depletion

ABSTRACT: cea06-02_folate - methotrexate treatment - global analysis of the folate metabolism in Arabidopsis - Treatment of cells of Arabidopsis by methotrexate which is an inhibitor of the synthesis of the folate. Consequently, the pool of folates presents a strong reduction. The goal of this project is to look at the variations of expression in the Arabidopsis genome and specifically in some genes implied in the metabolism of the folate. Keywords: time course,treated vs untreated comparison 10 dye-swap - CATMA arrays

Control of folate homeostasis is essential to sustain the demand for one-carbon (C1) units that are necessary for major biological functions, including nucleotide synthesis and methylation reactions. In this study, we analyzed the genome-wide and metabolic adaptive response of Arabidopsis (Arabidopsis thaliana) cells to folate depletion induced by the antifolate methotrexate. Drug treatment induced a response typical to xenobiotic stress and important changes in folate content and composition. T ...[more]

Interactions between H2O2 and glutathione in gene expression

Project description:rs08-03_glutathion - glutathion - How does glutathione content or reduction state affect H2O2-induced changes in the transcriptome? - Three single Arabidopsis mutants were used: cat2, knockout for catalase2 and so enriched in H2O2; cad2, defective in glutathione content; cytGR, knockout for cytosolic glutathione reductase. Cat2 was crossed with cad2 and cyt GR, and col0, 3 single mutants, and 2 double mutants were sampled in controlled growth conditions either in 8h or 16h photoperiod.

Differential expression in laccase mutants of Arabidopsis thaliana

Project description:ra10-01_laccases; laccase mutations. We demonstrated that laccases are involved in lignin polymerisation. Mutants have already been tested on microarrays and there is few differences compared to wild-type. The laccase mutation seems surgical. We possess a new double mutant, called snips, with a semi-dwarf phenotype, and we want to determine its profile. Each mutant was compared to wild type. All plants were harvested at the same developmental stage in the same growth chamber between 10h30 and 11h. 10 dye-swaps. CATMA arrays.
