Coexpression of the SWR1 components with EC. A to D, Circadian expression of SWR1 components and ELF3. Seedlings grown under neutral day conditions (12-h light: 12-h dark) for 2 weeks were transferred to continuous light conditions at ZT0. Whole seedlings were harvested from ZT24 to ZT68 to analyze transcript accumulation. Transcript levels of ARP6 (A), PIE1 (B), SEF (C), and ELF3 (D) were determined by RT-qPCR. Gene expression values were normalized to the eIF4A expression. Biological triplicates were averaged. Bars indicate the mean ± se. The white and gray boxes indicate the subjective day and night, respectively.
