The Arabidopsis pseudo-response regulator, APRR1, has a unique structural design
containing a pseudo-receiver domain and a C-terminal CONSTANS motif. This protein was …

Life on earth is shaped by the 24-h rotation of our planet around its axes. To adapt behavior
and physiology to the concurring profound but highly predictable changes, endogenous …

Circadian rhythms have been demonstrated in organisms across the taxonomic spectrum. In
view of their widespread occurrence, the adaptive significance of these rhythms is of interest …

Short-and long-distance circadian communication is essential for integration of temporal
information. However, a major challenge in plant biology is to decipher how individual …

Plants precisely time the onset of flowering to ensure reproductive success. A major factor in
seasonal control of flowering time is the photoperiod. The length of the daily light period is …

Summary The LATE ELONGATED HYPOCOTYL (LHY) transcription factor functions as part
of the oscillatory mechanism of the Arabidopsis circadian clock. This paper reports the …

The timing of floral transition has a direct impact on reproductive success. One of the most
important environmental factors that affect the transition is the change in day length …

In higher plants, the circadian clock orchestrates fundamental processes such as light
signaling and the transition to flowering. We isolated mutants of the circadian clock from an …

The genes coding for the response regulators ARR1 and ARR2 have previously been
identified by in silico screening of an expression sequence tag database and subsequent …

Circadian rhythms provide organisms with an adaptive advantage, allowing them to regulate
physiological and developmental events so that they occur at the most appropriate time of …
