Abstract

The circadian clock in plants regulates the rhythmic oscillation of not only protein coding genes but also introns, intergenic regions, and noncoding RNAs.

  • Circadian rhythms in plants are influenced by light and temperature signals.
  • The expression of various genetic elements, including noncoding RNAs, follows a rhythmic pattern linked to the circadian clock.
  • Different oscillators exist in separate parts of the plant, suggesting complex regulation of circadian synchronization.
  • These findings highlight the intricate mechanisms behind how plants adapt their physiological processes to daily and seasonal changes.
