Low temperature induction of Arabidopsis CBF1, 2, and 3 is gated by the circadian clock.
Exposing Arabidopsis (Arabidopsis thaliana) plants to low temperature results in rapid induction of CBF1, 2, and 3 (CBF1-3; also known as DREB1B, C, and A, respectively), which encode transcriptional activators that induce expression of a battery of genes that increase plant freezing and chilling tolerance. Recently, it has been shown that basal levels of CBF3 transcripts and those of certain C...
متن کاملTemperature Entrainment of the Arabidopsis Circadian Clock
Most eukaryotic organisms as well as some prokaryotes (cyanobacteria) have an endogenous circadian clock that keeps track of the earth’s 24-h day/night cycle and regulates the activity of numerous metabolic pathways. The existence of the circadian clock as an endogenous feature of organisms and not merely a response to the presence or absence of sunlight was recognized in plants as early as the...

متن کاملTranscriptional Regulation of LUX by CBF1 Mediates Cold Input to the Circadian Clock in Arabidopsis
Circadian clocks allow organisms to anticipate daily changes in the environment to enhance overall fitness. Transcription factors (TFs) play a prominent role in the molecular mechanism but are incompletely described possibly due to functional redundancy, gene family proliferation, and/or lack of context-specific assays. To overcome these, we performed a high-throughput yeast one-hybrid screen u...
متن کاملFBH1 affects warm temperature responses in the Arabidopsis circadian clock.
In Arabidopsis, the circadian clock allows the plant to coordinate daily external signals with internal processes, conferring enhanced fitness and growth vigor. Although external cues such as temperature can entrain the clock, an important feature of the clock is the ability to maintain a relatively constant period over a range of physiological temperatures; this ability is referred to as "temp...
