Sample GSM2634167 Query DataSets for GSM2634167
Status Public on Aug 21, 2017
Title Q120 developing seeds, 10-11 days after flower opening
Sample type RNA
 
Source name Arabidopsis thaliana recombinant inbred line Q120 developing seeds, 10-11 days after flower opening
Organism Arabidopsis thaliana
Characteristics tissue: developing seeds
genotype: Recombinant inbred line Q120
Stage: 10-11 days after flower opening
Treatment protocol Siliques of plants were harvested ten or eleven days after flower opening and immediately frozen in liquid nitrogen. Eight siliques each from six different plants were pooled for each of the recombinant inbred lines. The siliques were dissected and only the seeds were used for RNA extraction. For each of the recombinant inbred lines one sample was prepared.
Growth protocol A. thaliana seeds of 116 recombinant inbred lines were sown in pots with substrate 1 (Klasmann‐Deilmann GmbH, Geeste, Germany) and grown after stratification for 3 days at 4°C in long‐day conditions (16 h light at 20°C and 70% relative humidity/8 h dark at 16°C and 60% relative humidity). Light intensity during the light phase amounted to approximately 250 µE m−2 s−1. At least six plants per accession were grown.
Extracted molecule total RNA
Extraction protocol RNA was isolated from 200 mg samples of seeds. After grinding for 45 s at 27 Hz with Mixer Mill MM400 (Retsch GmbH, Haan, Germany) the samples were mixed with 0.7 ml extraction buffer (1 M Tris-HCl (pH 9.0), 1% (v/v) SDS, 10 mM EDTA (pH 8.0), 0.5% (v/v) β-mercaptoethanol in DEPC-H2O (0.1% (v/v)) and subsequently with 0.7 ml of phenol/chloroform/isoamyl alcohol (25:24:1). After centrifugation for 10 min, the aqueous phases were extracted once more with phenol/chloroform/isoamyl alcohol and then with chloroform. After adding 0.1 volume of 3 M sodium acetate (pH 5.4) and 2.5 volumes of 96% ethanol the samples were kept for 45 min at -80°C and then centrifuged for 5 min. The resulting RNA pellets were dissolved in 0.4-0.5 ml of DEPC-H2O (0.1% (v/v) and after centrifugation the supernatants were mixed with 1 volume of 4 M LiCl. After an overnight incubation on ice, RNA pellets were collected by centrifugation, washed in 1 ml each of 2 M LiCl, 96% and 70% ethanol, dried and dissolved in ribonuclase-free water. All centrifugation steps were carried out at 14,000 rpm and 4°C. Purification of RNA samples was achieved with RNeasy columns (Qiagen) and the peqGOLD OptiPure reagent (Peqlab Biotechnologie GmbH, Erlangen, Germany) according to manufacturer’s instructions.

Description Gene expression data, developing seeds of Arabidopsis thaliana recombinant inbred line Q120, 10-11 days after flower opening
A_Q120
Data processing The raw hybridisation intensity data files (‘CEL’ files) were directly imported into the RMAExpress 1.0.5 program (Irizarry et al. 2003) in order to carry out background correction, quantile normalisation and the transformation to log2 values with the normalisation approach robust multi-array average.
