| Title |
Soybean-Bayfield-2-RMA |
| Sample type |
RNA |
| |
|
| Source name |
Soybean strain Bayfield
|
| Organism |
Glycine max |
| Characteristics |
Strain: Bayfield
Growth stage: V2
|
| Biomaterial provider |
University of Guelph, Guelph, ON, Canada
|
| Growth protocol |
Grown in growth changers in ambient humidity, 16h photoperiod, and 25/19°C day/night temperatures. 10 seeds sown into two 20 cm pots.
|
| Extracted molecule |
total RNA |
| Extraction protocol |
At the V2 growth stage (Fehr et al. 1971), completely unrolled first trifoliate leaves were harvested by cutting the petiole a few millimeters below the leaflets, immediately frozen in liquid nitrogen and stored at -80°C. RNA was extracted using the RNeasy Plant Mini Kit (Quiagen, Valencia, CA).
|
| Label |
biotin
|
| Label protocol |
5µg of total RNA was used to generate double-stranded cDNA using a T7-linked oligo(dT) primer and SuperScript II reverse transcriptase (Invitrogen) following the instructions for the One cycle-cDNA synthesis kit (from Affymetrix). cRNA were synthesized using the IVT labelling kit from Affymetrix, resulting in biotinylated cRNA.
|
| |
|
| Hybridization protocol |
Target preparation, hybridization and scanning were carried out at the McGill University and Genome Quebec Innovation Centre Microarray platform using the protocol recommended by Affymetrix (). Labelled cRNA were cleaned and fragmented using the Sample Cleanup Module reagents (Qiagen). Spike controls B2, bio-B, bio-C, bio-D, and Cre-x were added to the hybridization cocktail before overnight hybridization at 45°C for 16 h.
|
| Scan protocol |
Arrays were washed and stained in an Affymetrix fluidics Station prior to scanning on the GeneChip Scanner 3000 (Affymetrix). Image acquisition and processing was done with the Microarray Analysis Suite 5.0 (Affymetrix).
|
| Description |
Sample 2 from the Bayfield soybean strain. The second of five samples for this strain.
|
| Data processing |
R and the BioConductor packages (Gentleman et al., 2004) such as affy, limma, cluster, and made4 were used for data analysis. This sample was pre-processed using the RMA method.
