Extended Data Fig. 3

Accumulation of (A) SIG5 and (B) psbD BLRP transcripts in the wild type (Ws), hy5, hyh and hy5 hyh double mutant. Experiments used 11-day old seedlings. All data represent means + /- s.e.m. of three independent biological replicates. Statistical comparison of each mutant with the wild type, at each timepoint, is provided above time-series plots, where *** = p < 0.001; ** = p < 0.01, * = p < 0.05 and n.s = not significant (one-way ANOVA followed by one-sided post-hoc Tukey test; 3 biological replicates; p values for panels A and B in Supplementary Data 1). (C) Quantification of luciferase bioluminescence after transient expression of SIG5::LUCIFERASE in wild type, hy5, hyh and hy5 hyh mutants, at two timepoints, using particle bombardment (n = 8 replicates per condition and genotype, except for Ws at ZT26 where n = 6; mean + /- s.e.m.). (D) Response of HY5 and HYH transcripts to a treatment of 3 h at 4 °C, given at two different timepoints, under free running conditions. Transcript levels normalized to ACT2 and confirmed with two other reference transcripts (not shown), 3 biological replicates show as mean + /- s.e.m; *** = p < 0.001; ** = p < 0.01, * = p < 0.05 and n.s = not significant in unpaired two-sided t-tests. p values for (D) are Col-0 HY5 (ZT25 0.002; ZT37 0.000), Ws HY5 (ZT25 0.001; ZT37 0.006), Col-0 HYH (ZT25 0.003; ZT37 0.000), Ws HYH (ZT25 0.000; ZT37 0.098).
