How LNK Clock Proteins Control Daily RNA Production by Directly Activating Gene Transcription in Arabidopsis

A multifunctional protein complex orchestrates rhythmic transcriptional activity in plants.

• The protein REVEILLE8 plays a key role in regulating the rhythms of transcription by binding to DNA through its MYB domain.
• REVEILLE8 recruits clock components known as LNKs to specific gene promoters, facilitating circadian gene expression.
• LNKs interact with RNA Polymerase II and the transcript elongation FACT complex, co-occupying target loci to regulate gene expression.
• The interaction among these components influences chromatin status and is essential for proper rhythms in newly formed RNA.
• Findings suggest a mechanism by which plants convert environmental signals into rhythmic gene expression patterns.
