Table 1 Description of TF transcripts co-expressed with PCD-related genes knocked down via VIGS and multiple comparisons of the mean relative cell death as responses of tobacco leaf discs following OA (20 mM, pH 7.0) treatment for 24 h as determined by Evans blue staining. Dye released from dead cells was measured at absorbance at 600 nm. Measurements were expressed as relative values with “one” corresponds to the maximum value and others are relative to it. Data are presented as means from two independent experiments with three replicates each. Red boxes indicate lower level of cell death in leaf discs, while blue box indicate higher level of cell death upon knock down of transcript as compared to leaf discs of the wild type non-transformed plant (WT) or those of plants transformed with pRTV2 only
