Transcripomics on the arabidopsis root tip during phosphate starvation-Transcripomics on the Arabidopsis Root tip during phosphate starvation

ABSTRACT: The objective of this project is to identify genes that are expressed in the Arabidopsis thaliana root tip and that are early induced (or repressed) by phoshate deficiency. Seedlings were germinated and grown (for 6 days) on phosphate rich medium and transfered to either a phosphate poor medium (Pi- = 20uM Pi treatment) or a phosphate rich medium (Pi+ = 500uM, Pi = control). Fifteen and 60 minutes after transfer, the tip (~800um) of the primary root was cut under a dissecting microscope. About 100 root tips per condition were harvested and there mRNA was analysed with the use of microarrays. 6 dye-swap - time course,treated vs untreated comparison

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.

Plates were stratified at 4C in the dark for 4 days. The plates were then transferred to a growth cabinet at 21C under a 16h light/8h darkness light regime, and the seedlings were harvested 18 days after transfer to the growth cabinet. 10 dye-swap - genotype comparaison

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.
