Plant cell wall and development. Comparison of transcript levels between elongating 5 and 11 day-old plants

ABSTRACT: rs05-11_hypocotyls - hypocotyls - Fine regulation of genes specifically expressed during cell elongation. - Seeds of A. thaliana were sowed on culture medium poured in Magenta boxes. They were allowed to germinate. Plantlets were in vitro for 5 or 11 days and harvested for RNA extraction. Keywords: organ comparison 3 dye-swap - CATMA arrays

<h4>Background</h4>Plant growth is a complex process involving cell division and elongation. Arabidopsis thaliana hypocotyls undergo a 100-fold length increase mainly by cell elongation. Cell enlargement implicates significant changes in the composition and structure of the cell wall. In order to understand cell wall biogenesis during cell elongation, mRNA profiling was made on half- (active elongation) and fully-grown (after growth arrest) etiolated hypocotyls.<h4>Results</h4>Transcriptomic ana ...[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.
