Some homologs of the angiosperm clock are conserved along the green lineage but may exhibit different functions, as observed in a flagellate chlorophyte alga.

Emerging tools and techniques provide insights into how the behavior and outputs of the circadian clock vary across the plant.

Crop genes that have been implicated in the modulation of photoperiodic flowering time and adaptation include orthologs of Arabidopsis core clock genes.

The circadian clock orchestrates the precise coordination of plant processes across daily and annual cycles of light and temperature, resulting in adaptation to local environments.

The mechanisms by which circadian clocks adjust to daily rhythms of light, dark, temperature, and internal metabolism are now coming to light.
