Figure 3.

ChIP-qPCR analysis was performed in the presence of preimmune serum or anti-SIG1 antibody using whole-cell extract prepared from wild type (Col-0) Arabidopsis thaliana grown under high light (1,200 μmol photons m^–2 s^–1) for 1 h after continuous normal light (50 μmol photons m^–2 s^–1). The levels of immunoprecipitated DNA of various promoter regions were calculated as percent recovery of total input DNA. Data are means ± SD of three experiments.
