Microarray analysis data for genes selected for this study
The microarray data shown for the genes listed suggests they are all UV-B stimulated (wild-type UV-B versus wild-type LW column; LW represents low fluence rate [25 μmol m−2 s−1] white light) and likely to be regulated by both UVR8 and HY5 (gene group A), neither UVR8 nor HY5 (gene group B), UVR8 only (gene group C), or HY5 only (gene group D). The HY5 and HYH transcription factors are shown in gene group E. Figures provided are FDR for the given comparisons (the higher expressing condition [i.e. wild-type UV-B in each case] is listed first) and indicate the expected percentage of false positives. For simplicity, RP scores are not shown. Complete microarray data are deposited in the National Center for Biotechnology Information Gene Expression Omnibus database (accession no. GSE3533). Full sets of data for columns 1 and 3 are presented in Supplemental Tables S1 and S2, respectively, and for column 2 in Brown et al. (2005).
