Analyses of differential transcription for the three different data set used in the microarray. (A) Principal Component Analysis (PCA) of the transcript profiles from all the melon samples in the microarray, showing a high separation for each experimental set up. The array data used for this analysis were normalized using the RMA algorithm implemented in the oligo R package for Nimblegen^® arrays. Pannels (B), (C) and (D) display support trees (ST) of the deregulated genes for all the conditions. (B) ST of the 937 deregulated genes with a q < 0.01 using the SAM in the 46d vs 15d melon fruit. (C) ST of the 198 deregulated genes with a q < 0.01 using the SAM in the M. cannonbalus infection. (D) ST of the 1182 deregulated genes with a q < 0.01 using the SAM in the CMV infection.
