Under Constant Red Light, HOS1 Is Required for Correct Expression of Clock Genes.

Plants were grown for 7 d under 12L:12D white-light cycles at 22°C followed by 2 d in 12L:12D red-light cycles at 17°C before being transferred to constant red light at 17°C for sampling in biological triplicate at the Zeitgeber time (ZT) times indicated. The cDNA were analyzed by qPCR three times for each biological replicate. Data presented are the average of three biological repeats ± se. Transcript abundance levels were normalized to ACT7. Blue diamonds with solid lines are data from the wild type (Col), whereas red squares with dotted lines are data from hos1-3.
