Temperature cycles set the phase of CAT3 but not of CAB2 over light cycles. Plants were grown for 14 days in 12 hr dark/12 hr light at 22°C (A and D; ⋄), 12 hr light/12 hr dark antiphase to 12 hr 22°C/12 hr 12°C (B and E; ▴), or 12 hr at 22°C/12 hr 12°C in LL (C and F; ○). Plants were then monitored for LUC activity on a Packard TopCount luminometer in LL at a constant temperature (22°C). Striped boxes represent dark and hatched boxes represent cold (equivalent to night); white boxes represent either light or hot. Representative CAB2::LUC traces in A–C and CAT3::LUC traces in D–F were taken from two independent experiments that yielded consistent results.
