| Hybridization protocol |
Hybridization was carried out according to a direct comparative loop design
|
| Scan protocol |
Image acquisition was performed with a GenePix® scanner and quantified with the in-built software
|
| Description |
Biological replicate 1 of 3. Control cultivar 4 was hybrized with the treatment cultivar 4 on the spotted oligo-array as a part of a microarray loop design.
|
| Data processing |
Data were background corrected with the minimum method, print-tip lowess (within-array) normalized and scaled (between-array) from log2 of processed red signal/processed green signal
Quality check was performed with the MapMan Robin software. Data were processed and analysed with the web-based application CarmaWeb
Data Analysis: The normalized intensities within an array and between replicates were averaged to one single value per gene. Differentially expressed genes were determined with the limma paired moderate t-test. Adjusted p-values were generated according to the Benjamini and Hochberg (BH) method.
