Table I. Summary of luciferase activities at the peak (3 h) of the UV-B response

The effect of a pulse of UV-B irradiation on luciferase activity (average and sd of three or more independent transgenic lines) is shown as FC at the highest values around 3 h (2–4 h) after the UV-B pulse. For the native promoter, results of three independent assays of one representative transgenic line are shown. FCs comparable to the native promoter (38.6-fold [77.2 × 0.5] to 154.4-fold [77.2 × 2]) are highlighted in bold. All the constructs are illustrated in Figure 2.
