The plant circadian clock coordinates the responses to multiple and often simultaneous
environmental challenges that the sessile plant cannot avoid. These responses must be …

Life is a cyclical chemical process that is regulated in four dimensions. We distinguish parts
of the cycle: development describes the changes from single cell to adult, and aging the …

Circadian regulation is critically important in maintaining metabolic and physiological
homeostasis. However, little is known about the possible influence of the clock on …

Young sunflower plants track the Sun from east to west during the day and then reorient
during the night to face east in anticipation of dawn. In contrast, mature plants cease …

Like most organisms, plants have endogenous biological clocks that coordinate internal
events with the external environment. We used high-density oligonucleotide microarrays to …

Plants have evolved complex and sophisticated transcriptional networks that mediate
developmental changes in response to light. These light-regulated processes include …

Abstract The CIRCADIAN CLOCK ASSOCIATED 1 (CCA1) gene encodes a MYB-related
transcription factor involved in the phytochrome induction of a light-harvesting chlorophyll …

The circadian clock regulates diverse aspects of plant growth and development and
promotes plant fitness. Molecular identification of clock components, primarily in …

Flowering of Arabidopsis is promoted by long days and delayed by short days. Mutations in
the GIGANTEA (GI) gene delay flowering under long days but have little or no effect under …

The dominant late elongated hypocotyl (lhy) mutation of Arabidopsis disrupted circadian
clock regulation of gene expression and leaf movements and caused flowering to occur …
