Fig. 2: Temperature affects different aspects of the circadian system.
From: Integrating temperature into the Arabidopsis circadian system
The plant circadian clock comprises at least three families of transcription factors that reciprocally regulate promoter activity, ultimately generating a biological timer with an approximate 24-h period. Distinct mechanisms of temperature-modulated regulation have been characterised for certain genes within the circadian clock, although these are not mutually exclusive, and doubtless additional regulations will be elucidated over time.
