|
| Label |
Cy5
|
| Label protocol |
Aminoallyl-RNA was labeled with Cy5 following the "Amino Allyl MessageAmp II aRNA Amplification Kit" protocol (Applied Biosystems/Ambion, Austin, USA).

| Channel 2 |
| Source name |
F047
|
| Organism |
Zea mays |
| Characteristics |
inbred line: F047
cultivar: flint
tissue: seedling
age: 7 day
sample type: pool of 5 biological replicates
|
| Growth protocol |
Regulated growth conditions (25℃ 16h-day, 21℃ 8h-night, 70% air humidity) in a climate chamber (Percival Scientific Inc., Perry, USA) for seven days.

|
| Label |
Cy3
|
| Label protocol |
Aminoallyl-RNA was labeled with Cy3 following the "Amino Allyl MessageAmp II aRNA Amplification Kit" protocol (Applied Biosystems/Ambion, Austin, USA).
|
| |
|
| |
| Hybridization protocol |
The hybridization and post-hybridization followed the protocol of the Maize Oligo Array Project (http://www.maizearray.org/).
|
| Scan protocol |
The slides were scanned using an AppliedPrecision ArrayWorx Scanner (Applied Precision Inc., USA).
|
| Description |
Gene expression data from European maize inbred lines (14 dent, 7 flint)
|
| Data processing |
Raw data from microarray hybridization, exported from GenePix suites 6.0 (Axon, USA), was imported into LIMMA. The background was corrected by normexp method with offset 50. Background-corrected signal intensities were normalized using a two-step normalization: print-tip group loss (within-array normalization) and then between-array scale normalization.
