Dependence of recombination frequency (A) and amount of CPDs (B) on the light quality after UV-B irradiation. White bars represent the photolyase mutant A94 (uvr2–1/GUS), and black bars indicate the corresponding wild-type A87 (UVR2–1/GUS). Recombination frequencies were determined in both lines after irradiation with UV-B for 30 min (Fig. 1A, WG 295) and subsequent exposure to various light qualities as indicated. UV-A/R, 2 h UV-A, then transferred for 22 h to red light; R, red light; FR, far red light; D, darkness; no-UV-B, untreated control. The amount of CPDs in plants was determined 24 h after UV-B irradiation.
