Seven-day-old white-light-grown Arabidopsis seedlings were exposed for 15 minutes to polychromatic radiation with decreasing short-wave cut-off in the UV range, transferred back to the standard growth chamber and samples were taken 1 and 6 hours after the start of irradiation.
Genome-wide analysis of gene expression reveals function of the bZIP transcription factor HY5 in the UV-B response of Arabidopsis.
