The first described feedback loop of the Arabidopsis circadian clock is based on reciprocal
regulation between TIMING OF CAB EXPRESSION 1 (TOC1) and CIRCADIAN CLOCK …

Transcriptional feedback loops constitute the molecular circuitry of the plant circadian clock.
In Arabidopsis, a core loop is established between CCA1 and TOC1. Although CCA1 …

It has been proposed that CIRCADIAN CLOCK ASSOCIATED 1 (CCA1) and LATE
ELONGATED HYPOCOTYL (LHY) together with TIMING OF CAB EXPRESSION 1 (TOC1) …

Circadian clocks rhythmically coordinate biological processes in resonance with the
environmental cycle. The clock function relies on negative feedback loops that generate 24 …

Little is known about plant circadian oscillators, in spite of how important they are to sessile
plants, which require accurate timekeepers that enable the plants to respond to their …

The interactive regulation between clock genes is central for oscillator function. Here, we
show interactions between the Arabidopsis clock genes LATE ELONGATED HYPOCOTYL …

Circadian clocks synchronise biological processes with the day/night cycle, using molecular
mechanisms that include interlocked, transcriptional feedback loops. Recent experiments …

Background 24-hour biological clocks are intimately connected to the cellular signalling
network, which complicates the analysis of clock mechanisms. The transcriptional regulator …

The toc1 mutation causes shortened circadian rhythms in light-grown Arabidopsis plants.
Here, we report the same toc1 effect in the absence of light input to the clock. We also show …

To examine the role of the TOC1 (TIMING OF CAB EXPRESSION1) gene in the Arabidopsis
circadian system, we generated a series of transgenic plants expressing a gradation in …
