Hyperlink to a UVB receptor: Rizzini et al. (2011) Figure 3. ßGlu and cyclobutane pyrimidine dimer (CPD) induction in response to varied UV spectral ranges. Plants were irradiated for 15 min (black bars) or 30 min (gray bars) under the UV source, using transmission cut-off filters and then kept in red light for 24 h for measurement of ßGlu induction. For analysis of CPDs, samples were taken from leaves in dim yellow light immediately after irradiation. A, Accumulation of ßGlu I protein after 30 min of UV irradiation. The apparent size of the major 34-kD immunoreactive band is indicated at the right. B, Induction of CPDs. Representative experiment that was repeated twice with similar results. C, Induction of ßGlu activity. Mean values and SE of two independent experiments (n=8).
