Table 1 Redox regulation of Rap2.4 transcriptional activation

From: The redox-sensitive transcription factor Rap2.4a controls nuclear expression of 2-Cys peroxiredoxin A and other chloroplast antioxidant enzymes

  Control 1 mM H2O2 1 mM DTT 1 mM Asc
35S:Rap2.4a 180 ± 30 %* 279 ± 56 %* 67 ± 11 %* 63 ± 10 %*
35S:CFP 100 ± 24 % 137 ± 18 %* 68 ± 9 %* 61 ± 11 %*
Rap2.4a/CFP 180 ± 29 %* 203 ± 38 %* 99 ± 10 % 103 ± 11 %
  1. Relative luciferase activity (mean ± SD) in mesophyll protoplasts from transgenic Arabidopsis expressing luciferase under control of the 2CPA promoter, 2 h after transfection with either 35S:Rap2.4a or 35S:CFP, and 1.5 h after application of 1 mM H2O2, DTT and ascorbate, respectively. Significance of difference (P > 0.01; Student's T-Test; n = 72) is indicated by asterisks.
