Relative transcript levels of A. thaliana ROS1 and DDM1 genes measured by qRT-PCR. Plants were irradiated with UV-B light for 4 h (UV-B) or kept under control conditions (C) as indicated in Materials and Methods. CPK3 transcript was used for normalization and UVR2 as a control of a UV-B inducible gene. Data show mean values ± S.E.M. of at least three independent experiments.
