Transcriptional 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...

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...

Rethinking Transcriptional Activation in the Arabidopsis Circadian Clock

Circadian clocks are biological timekeepers that allow living cells to time their activity in anticipation of predictable daily changes in light and other environmental factors. The complexity of the circadian clock in higher plants makes it difficult to understand the role of individual genes or molecular interactions, and mathematical modelling has been useful in guiding clock research in mod...

Regulation of circadian clock transcriptional output by CLOCK:BMAL1

The mammalian circadian clock relies on the transcription factor CLOCK:BMAL1 to coordinate the rhythmic expression of 15% of the transcriptome and control the daily regulation of biological functions. The recent characterization of CLOCK:BMAL1 cistrome revealed that although CLOCK:BMAL1 binds synchronously to all of its target genes, its transcriptional output is highly heterogeneous. By perfor...

LUX ARRHYTHMO Encodes a Nighttime Repressor of Circadian Gene Expression in the Arabidopsis Core Clock

Circadian clocks provide an adaptive advantage by allowing organisms to anticipate daily and seasonal environmental changes [1, 2]. Eukaryotic oscillators rely on complex hierarchical networks composed of transcriptional and posttranslational regulatory circuits [3]. In Arabidopsis, current representations of the circadian clock consist of three or four interlocked transcriptional feedback loop...
