Sample GSM940624 Query DataSets for GSM940624
Status Public on Jun 01, 2012
Title PI null mutant perturbation 10
Sample type RNA
 
Channel 1
Source name day5 pi set3
Organism Arabidopsis thaliana
Characteristics tissue: early-intermediate floral stage ~ stage 5-6 flowers
developmental stage: 5 days after Dexamethasone treatment (early-intermediate floral stage ~ stage 5-6 flowers)
genotype: FIS (ap1 cal AP1-GR); pi-1 homozygous
treatment: 20 degrees (constant)
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.
 
Channel 2
Source name day5 PI set3
Organism Arabidopsis thaliana
Characteristics tissue: early-intermediate floral stage ~ stage 5-6 flowers
developmental stage: 5 days after Dexamethasone treatment (early-intermediate floral stage ~ stage 5-6 flowers)
genotype: FIS (ap1 cal AP1-GR); pi-1 heterozygous
temperature: 20 degrees (constant)
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.

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 20-25) pooled per replicate and genotype
Data processing Agilent Feature Extraction Software (v 9.5.3.1) was used for background subtraction and LOWESS normalization
