  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.
