Plant species have evolved different requirements for environmental/endogenous cues to
induce flowering. Originally, these varying requirements were thought to reflect the action of …

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 …

The circadian clock is required for adaptive responses to daily and seasonal changes in
environmental conditions,,. Light and the circadian clock interact to consolidate the phase of …

Plants initiate senescence to shed photosynthetically inefficient leaves. Light deprivation
induces leaf senescence, which involves massive transcriptional reprogramming to …

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 …

Phytochromes are red (R)/far-red (FR) light photoreceptors that play fundamental roles in
photoperception of the light environment and the subsequent adaptation of plant growth and …

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

The earth rotates on its axis every 24 h, with the result that any position on the earth's
surface alternately faces toward or away from the sun—day and night. That the metabolism …

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 is a widespread cellular mechanism that underlies diverse rhythmic
functions in organisms from bacteria and fungi, to plants and animals. Intense genetic …
