| Hybridization protocol |
Potato cDNA microarrays were prehybridized for 45 min in prehybridization buffer (5X SSC, 0.1% SDS, 1% BSA) preheated at 42°C. Prehybridized slides were washed twice in miliQ water for 5 min each, then washed for 2 min in isopropanol and air dried. Labelled cDNA probes were dissolved in 45 µl of 1X hybridization buffer (50% formamide, 5X SSC, and 0.1% SDS). 2 µl of EDTA (from 0.5M stock), 2 µl of polyA DNA (from 10 µg/ µl stock) and 0.75 µl of salmon sperm DNA (from 10 µg/µl stock) were added into the probe mix. Heat denatured probes were carefully applied to the microarray slides and incubated in hybridization chamber at 42°C for 16-20h. Hybridized slides were washed for 5 min in a low stringency wash buffer (2X SSC and 0.1% SDS) preheated to 42°C, followed by 10 min wash in a high-stringency wash buffer (0.05X SSC and 0.1% SDS) at room temperature. Slides were washed four times for one min each in 0.05X SSC, and dried using centrifuge.
|
| Scan protocol |
Scanned on GenePix Personal 4100A scanner (Molecular Devices Corporation, Sunnyvale, CA). Images were quantified using using GenePix Pro 6.0 (Molecular Devices Corporation, Sunnyvale, CA).

| Description |
64_MA5-KB6
Dye swap Replicate of 63_KB5-MA6, Total RNA from shoot tip including first unopened leaf of Tall Mokka and Typica.
|
| Data processing |
Per spot and per chip normalization based on the Lowess method was implemented using GeneSpring 7.0 (Agilent Technologies, Santa Clara, CA). Statistically significant differentially expressed genes were identified by applying one-way ANOVA analysis.
