Newly Described Components and Regulatory Mechanisms of Circadian Clock Function in Arabidopsis thaliana

The circadian clock regulates a significant proportion of the genome in plants.

• Clock components and regulatory mechanisms influence rhythmic metabolic and physiological activities in plants.
• Transcriptional/translational feedback loops are central to the circadian clock's function.
• Recent studies show that clock protein complex formation affects plant growth regulation.
• Alternative splicing has been identified as a new regulatory mechanism for circadian clock function.
• Key properties like temperature compensation provide new insights for research on plant circadian rhythms.
• Connections between the circadian clock and metabolism, hormone signaling, and stress responses add complexity to plant growth regulation.
