Sample GSM187242 Query DataSets for GSM187242
Status Public on May 09, 2007
Title Col-O_HL_A
Sample type RNA
 
Source name Col-O, 3 hours high light
Organism Arabidopsis thaliana
Characteristics Col-O, 7 d old seedlings
Treatment protocol For high light treatment seedlingswere transferred for 3 h 1000 micro mol quanta m-2 s-1 (metal halide HQI-T 400 W daylight light bulbs, Osram).
Growth protocol Arabidopsis thaliana seeds were sterilized (75 % ethanol, 0.01 % Triton X-100) for 15 min and washed three times with 95 % ethanol before spreading onto 0.27 % phytoagar plates containing 1x Murashige and Skoog basal salt mixture including vitamins (Duchefa) and 2 % sucrose. The plates were stratified two days in darkness at 4°C and then placed 7 d into continuous white light (100 micro mol quanta m-2 s-1, 22 °C).
Extracted molecule total RNA
Extraction protocol For total RNA isolation the RNeasy Plant Mini Kit (QIAGEN) was used according to the manufacturer’s instructions. The concentration of total RNA was determined with a Nanodrop ND-1000 spectrophotometer; quality of RNA was checked by agarose gel electrophoresis
Label Biotin
Label protocol 5 μg of total RNA was used in a reverse transcription reaction (Ambion MessageAmp kit) to generate first-strand cDNA. After second-strand synthesis, double-stranded cDNA was used in an in vitro transcription reaction to generate biotinylated cRNA. The quality of purified and fragmented cRNA was assessed by spectrophotometry and agarose gel electrophoresis.
 
Hybridization protocol 15 μg of fragmented, biotinylated cRNA was used for hybridization. Hybridization was performed as in the Affymetrix technical manual.
Scan protocol Washing, staining, and scanning procedures were performed as described in the Affymetrix technical manual. A Hybridization Oven 640, a Fluidics Station 450 and a GeneChip Scanner 3000 were used.
Description Part of an experiment investigating transcriptome changes in of wt, cry1 and hy5 after high light and in wt after blue light treatment.
Data processing Normalization and expression estimate computation were calculated from the .CEL output files from the Affymetrix GCOS 1.1 software using gcRMA implemented in R using standard settings. Statistical testing for differential expression was performed with logit-t analysis (p < 0.025; (21)). The .CHP and logit-t files were loaded into GeneSpring 7.3 (Agilent Technologies). Affymetrix present, marginal and absent flags were used as an indicator of whether or not a gene was expressed. Genes called absent in both of the
compared conditions were removed from subsequent analyses.
