Sample GSM160815 Query DataSets for GSM160815
Status Public on Feb 02, 2008
Title drought control rep3
Sample type RNA
Source name Crown
Organism Hordeum vulgare
Characteristics drought control
Treatment protocol Drought treatment began seven days after sowing and lasted for 21 days. Soil Water Content (SWC) was calculated relative to the field capacity of the soil by weighing at regular intervals. Control (91 % SWC) and stressed samples were collected at soil water contents of approximately 68%, 38%, 20%, 11% and 9% SWC.
Growth protocol Barley (Hordeum vulgare) cv. Morex plants were grown in steam-sterilized soil in a growth chamber (Model GC-15, EGC Chagrin Falls, OH) with 12 h photopheriod (148 µmol m-2 s-1 average photosynthetic active radiation) at 23ºC, 12 h dark at 20ºC and 70% relative humidity.
Extracted molecule total RNA
Extraction protocol Total RNA was isolated using TRIzol reagent (Invitrogen) from frozen crown samples taken from above soil tissue excluding most fully extended lamina. The protocol is available on the Arabidopsis Information Resource website at RNA was purified using Qiagen RNeasy spin columns with DNase treatment. Quality was assessed by running 25-250 ng on a RNA Lab-On-A-Chip (Caliper Technologies) using an Agilent Bioanalyzer 2100 (Agilent Technologies).
Label Biotin
Label protocol The BioArray High-Yield RNA Transcript Labeling Kit (Enzo Diagnostics) was then used to synthesize biotin-labeled cRNA from template cDNA by in vitro transcription.
Hybridization protocol 10 µg labeled, fragmented cRNA was hybridized at 45°C with rotation for 16 hours in an Affymetrix GeneChip Hybridization Oven 320 on Affymetrix Barley1 Genechip arrays. The arrays were washed and stained using streptavidin phycoerythrin on an Affymetrix Fluidics Station 400.
Scan protocol The arrays were scanned on a Hewlett-Packard GeneArray scanner.
Description drought control
Data processing MAS files from the GCOS software were used for determining the ‘present’ gene list. Probe set intensity values above the level set by the gcRMA normalization processor were imported into GeneSpring GX 7.3 software (Silicon Genetics, CA, USA), which was used for the rest of the analysis.
