Sample GSM503937 Query DataSets for GSM503937
Status Public on Apr 02, 2010
Title AP1-GRap1cal_8hr_Mock vs Dex_set5
Sample type RNA
 
Channel 1
Source name AP1-GRap1cal_8hr Mock_set5
Organism Arabidopsis thaliana
Characteristics genome/variation: AP1-GR ap1 cal inflorescences
treatment group: Mock
treatment time: 8hr
Treatment protocol For all experiments, we used approximately 4 week-old 35S:AP1-GR ap1-1 cal-1 plants. For each sample, inflorescence tissue from ~25 plants was collected using jeweler’s forceps. Four biologically independent sets of samples were generated. Inflorescences were treated with a solution containing 10 μM dexamethasone (Sigma-Aldrich), 0.01% (v/v) ethanol, and 0.015% (v/v) Silwett L-77 (De Sangosse), or with an identical mock solution that lacked dexamethasone. We then collected inflorescence tissue after 2, 4, 8, and 12 hours, as well as from untreated plants (0 hour time point).
Growth protocol Plants were grown on a soil:vermiculite:perlite (2:1:1) mixture at 20ºC 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. Quality of RNA samples was evaluated using a Bioanalyzer and a RNA Nano 6000 kit (Agilent). RNA concentrations were determined using a Nanodrop ND-1000 spectrophotometer (Thermo Fisher Scientific).
Label Cy3
Label protocol Agilent microarrays were used following manufacturer's instructions. RNA samples were labeled with fluorescent dyes using the Quick Amp Labeling Kit (Agilent).
 
Channel 2
Source name AP1-GRap1cal_8hr Dex_set5
Organism Arabidopsis thaliana
Characteristics genome/variation: AP1-GR ap1 cal inflorescences
treatment group: Dex
treatment time: 8hr

Label Cy5
Label protocol Agilent microarrays were used following manufacturer's instructions. RNA samples were labeled with fluorescent dyes using the Quick Amp Labeling Kit (Agilent).
 
 
Hybridization protocol Agilent microarrays were used following manufacturer's instructions. Microarray hybridizations (65ºC, 16h) and washes were performed with Agilent reagents and following standard protocols.
Scan protocol Microarrays were scanned using an Agilent DNA Microarray Scanner G2565CA, and data were acquired using Agilent's Feature Extraction Software version 9.5.3.1.
Description GEC_251778410021_S01_GE2-v5_95_Feb07_1_4.txt
Data processing Data were processed with the Resolver version 7.1 data analysis system (Rosetta Biosoftware, Seattle, WA), using the Agilent Ratio data processing pipeline with default settings. Resolver uses an error model-based approach to stabilize the variance estimation to improve the specificity and sensitivity in differential gene expression detection (Weng, L., Dai, H., Zhan, Y., He, Y., Stepaniants, S.B., and Bassett, D.E. (2006). Rosetta error model for gene expression analysis. Bioinformatics 22, 1111-1121).
