Sample GSM298093 Query DataSets for GSM298093
Status Public on Oct 01, 2008
Title Crown tissue of Solstice at 5 weeks post germination
Sample type RNA
 
Source name Solstice crown 5 weeks post-germination (no vernalisation)
Organism Triticum aestivum
Characteristics variety: Solstice
Grown for three weeks with 14 hour photoperiod; 16°C day 14°C night; PAR = 280 then an additional 2 weeks with declining day-length and light intensity only.
Growth protocol Seeds were planted in 50:50 potting compost:perlite in 10 cm pots and maintained in growth cabinets with a 14 h photoperiod (PAR 280) and 16°C day/14°C night. After three weeks of these conditions, plants were gradually exposed to a decline in temperature, day-length and light intensity: week 3-4 = 14 h photoperiod (PAR 280), 14°C day/12°C night; week 4-5 = 12 h photoperiod (PAR 185), 14°C day/10°C night;week 5--6 = 11 h photoperiod (PAR 185), 12°C day/10°C night;week 6-7 = 11 h photoperiod (PAR 185), 12°C day/8°C night;week 7-8 = 10 h photoperiod (PAR 95), 10°C day/6°C night;week 8-9 = 9 h photoperiod (PAR 95), 8°C day/4°C night;week 9-10 = 8 h photoperiod (PAR 95), 6°C day/2°C night;week 10-11 = 8 h photoperiod (PAR 95), 4°C day/2°C night;week 11-12 = 8 h photoperiod (PAR 48), 2°C day/2°C night.
Extracted molecule total RNA
Extraction protocol Trizol extraction of total RNA was performed according to the manufacturer's instructions.
Label Biotin
Label protocol Biotinylated cRNA were prepared according to the standard Affymetrix protocol from 5 ug total RNA (Expression Analysis Technical Manual, 2001, Affymetrix).
 
Hybridization protocol Following fragmentation, 10 ug of cRNA were hybridized for 16 hr at 45C on GeneChip Wheat Genome Array. GeneChips were washed and stained in the Affymetrix Fluidics Station 400.
Scan protocol GeneChip Wheat Genome Arrays wee scanned with the GeneChip 3000.
Description CONTROL sample to allow separation one to distinguish cold induced responses in gene expression from those that result from a decline in day-length and light.
Data processing The data were analysed using GeneSpring GX 7.3: raw data was imported from .CEL files and normalised using RMA. Within GeneSpring GX, per gene normalisation to the median was perfored.
