How Different Parts of a Plant Control Its Daily Biological Clock

Circadian dynamics may vary significantly across different organs and tissues.

• The plant circadian clock generates 24-hour rhythms in gene expression.
• Evidence suggests spatial variation in the regulation of the circadian clock.
• Differences in sensitivity to environmental cues may influence clock timing.
• Local cellular rhythms may be coordinated to maintain overall timing in the organism.
• Spatial regulation of the clock could play a role in controlling various developmental processes.
