A small-molecule clock modulator quantitatively manipulates photoperiodic flowering

Key Points

• The aim is to understand how a small-molecule clock modulator influences flowering in plants.
• Utilized a CK1 inhibitor to manipulate flowering.
• Assessed the impact on circadian period length.
• Evaluated the critical day-length for flowering under varying doses.
• The CK1 inhibitor significantly lengthened the circadian period.
• It altered the critical day-length for flowering in a dose-dependent manner.
