| Title |
dex induction of 35-PLT1-GR, biological rep 3 |
| Sample type |
RNA |
| |
|
| Source name |
whole seedlings
|
| Organism |
Arabidopsis thaliana |
| Characteristics |
genotype/variation: 35-PLT1-GR
tissue: whole seedlings
treatment: dexamethasone
treatment time: 6 hrs
|
| Treatment protocol |
The next day, dex was added to each of the flasks to a final concentration of 10 µM except the mock samples to which an equal amount of DMSO was added. Each genotype was induced with 5 minute intervals which meant that all samples were harvested within half an hour to minimize the effect of time of day on the resulting transcriptome. After 6 hour induction seedlings were quickly harvested through a sieve, transferred briefly onto liquid absorbing paper and flash frozen in liquid nitrogen. In a separate experiment 35S::PLT2-GR seedlings were treated as described above with dex and, as a mock control, DMSO.
|
| Growth protocol |
35S::PLT[1,3,4,5,7]-GR seedlings were germinated on 0.5x GM agar and four day old seedlings of each genotype were subsequently divided in 3 batches (representing three biological replicates) of ~50 seedlings into 50 ml liquid 0.5x GM in erlenmeyer flasks. We chose the 35S::PLT4-GR line to be used as mock sample and for this line an additional 3 erlenmeyer flasks were prepared. Seedlings were cultured overnight under mild shaking (~75 rpm).

| Extracted molecule |
total RNA |
| Extraction protocol |
RNA was extracted from the seedlings using the Spectrum Plant Total RNA kit (Sigma-Aldrich) and used for microarray hybridisation.
