Microarray experimental design. Hybridizations performed with samples from the tree genotypes. Two biological replicates were analysed per genotype and arrows illustrates each hybridization (four per biological replicate, two labelled with Cy3 and two with Cy3, and two against each of the other genotypes), in total twelve hybridizations.
