Relative expression data (transgenic to wild-type or treatment to control) for the 20 most deregulated genes of clusters I and II are presented. The induction/suppression of each gene by HL treatment in the hpAtPARP2 plants or catalase-deficient plants (CAT2HP1) or by the different oxidative stress-causing treatments (H2O2 spray, ozone fumigation, or syringolin treatment) is indicated. Expression data of transcripts with calls absent in both control and transgenic plants are indicated with A. Data were partly obtained with Genevestigator (27).
