Accumulation of transcripts from six target loci was analyzed by RT-qPCR in WT (L5 background) control plants, med14-3, uvh6-3 mutants, and med14-3 uvh6-3 double mutants at 23 and 37°C. The primer pairs for the following targets potentially amplify multiples copies, indicated between brackets: ATCOPIA28 (AT1TE43225 and AT3TE51900) and ONSEN (AT3TE54550, AT3TE92525, AT5TE15240, AT1TE12295, AT1TE24850, AT1TE59755, and AT1TE71045). Data were normalized to the reference gene AT5G12240 and further normalized to the mean of WT samples at 23°C. Error bars illustrate standard errors of the mean across three biological replicates. For each temperature treatment, statistical differences between means of mutant conditions were tested using ANOVA followed by post hoc analysis using Tukey's honest significant difference test (*P < 0.05, **P < 0.005, ***P < 0.0001). see the Materials and Methods section. Data for the L5-GUS transgene was already displayed in Fig 2B.
