| Title |
AP3 temperature sensitive perturbation 9 |
| Sample type |
RNA |
| |
|
| Channel 1 |
| Source name |
wholeInf AP3 set3 27deg
|
| Organism |
Arabidopsis thaliana |
| Characteristics |
tissue: whole inflorescences (not in the floral induction system) up to approx. stage 10 flowers
developmental stage: whole inflorescences (not in the floral induction system) up to approx. stage 10 flowers
genotype: L-er wt
treatment: 16 degrees (constant) + shifted to 27 degrees for 24 hrs
genetic background: Ler
|
| Treatment protocol |
For all experiments, ~4 week-old plants were used. For experiments using the FIS (35S:AP1-GR ap1-1 cal-1 plants), flower development was induced using a solution containing 10 μM dexamethasone (Sigma-Aldrich), 0.01% (v/v) ethanol and 0.015% (v/v) Silwet L-77 (De Sangosse) – as described in Wellmer F, et al. (2006) Genome-Wide Analysis of Gene Expression during Early Arabidopsis Flower Development. PLoS Genetics 2(7):e117.
|
| Growth protocol |
Plants were grown on a soil:vermiculite:perlite (3:1:1) mixture at 20 degrees (16 degrees for plants used for temperature-sensitive perturbation experiments) under constant illumination with cool white fluorescent light
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Total RNA was isolated from tissue samples using the Plant Total RNA kit (Sigma-Aldrich), according to the manufacturer's instructions
|
| Label |
Cy5
|
| Label protocol |
500ng of total RNA were primed with 0.6µl of T7 DNA primer at 65°C for 10 min, then reverse transcribed at 40°C for 2 hrs in the presence of 300 U MMLV Reverse Transcriptase and 10mM dNTP mix, with Cy3-label and Cy5- label.

| |
| Hybridization protocol |
Fragmentation buffer and Hybridization Buffer HI-RPM (Agilent Gene Expression Hybridization Kit) were added and samples were applied to microarrays enclosed in Agilent SureHyb-enabled hybridization chambers and hybridized for 16 hrs at 65°C. After hybridization, slides were washed sequentially according to the manufacturer's instruction.
|
| Scan protocol |
Scanned on an Agilent G2565AA scanner. Images were quantified using Agilent Feature Extraction Software (v 9.5.3.1).
|
| Description |
Biological Replicate 3: several plants (approx 25-30) pooled per replicate and genotype
|
| Data processing |
Agilent Feature Extraction Software (v 9.5.3.1) was used for background subtraction and LOWESS normalization
