Venn diagrams depicting the distribution of induced (≥ 2.5 fold) and repressed (≤ -2.5 fold) genes in PPV-infected protoplasts at three different time points. A statistical cut-off with a FDR at 5% that corresponds to Q ≤ 0.05, after Benjamini and Hochberg's correction was used to determine genes significantly differentially regulated in protoplasts transfected with a PPV infectious cDNA clone, pPPV-SK68 at 3, 6 and 12 hours post transfection (hpt). The number of genes in the non-overlapping sector represents unique significant genes at each time point, while the overlapping sectors represent genes that are in common at time points indicated. The number in parentheses in the Venn diagram circles corresponds to the genes induced or repressed in the PPV infected leaves.
