|
| Description |
Gene expression data from maize kernel
|
| Data processing |
Raw data from microarray hybridization, exported from GenePix suites 6.0 (Axon, USA), was imported into LIMMA with annotation and spot types. Spots with a negative flag value were assigned a weight of 0.1 in the subsequent analysis. Background-subtracted signal intensities were normalized using a two-step normalization: print-tip group loss (within-array normalization) and then between-array scale normalization.
