Body Clocks from Multiple Internal Timers: Insights from Different Living Things

AI simplified

Abstract

Organisms with differentiated tissues can coordinate different rhythms through partitioned clock functions.

  • Circadian clocks are found universally across diverse organisms, including bacteria, fungi, plants, and animals.
  • Unicellular organisms possess independent clocks that generate 24-hour rhythms for various biological processes.
  • Multicellular organisms can divide clock functions among different tissues to produce coordinated rhythms.
  • Temporal coordination in systems with multiple oscillators is crucial for maintaining stable circadian rhythms of gene expression and biological activity.
