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 …

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

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 …

In many organisms, the circadian clock is composed of functionally coupled morning and
evening oscillators. In Arabidopsis, oscillator coupling relies on a core loop in which the …

The underlying mechanism of circadian rhythmicity appears to be conserved among
organisms, and is based on negative transcriptional feedback loops forming a cellular …

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 …

Flowering is often triggered by exposing plants to appropriate day lengths. This response
requires an endogenous timer called the circadian clock to measure the duration of the day …

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 …

The coordination of developmental and physiological events with environmental signals is
facilitated by the action of the circadian clock. Here we report a new set of circadian clock …

Several organisms have evolved the ability to measure daylength, or photoperiod, allowing
them to adjust their development in anticipation of annual seasonal changes. Daylength …
