study demonstrates that FKF1 protein stabilizes CONSTANS (CO)protein in the afternoon in long days; together with CO transcriptional regulation, FKF1 protein controls robust FLOWERING LOCUS T FT) mRNA induction through multiple feedforward mechanisms that accurately control flowering timing
Title: FKF1 conveys timing information for CONSTANS stabilization in photoperiodic flowering.

Both LKP2 and ZTL suppress early flowering, especially under short-day (noninductive) conditions, and that such suppression is dependent on FKF1.
Title: LOV KELCH PROTEIN2 and ZEITLUPE repress Arabidopsis photoperiodic flowering under non-inductive conditions, dependent on FLAVIN-BINDING KELCH REPEAT F-BOX1.

This result indicates that the conformational change in the loop region represents a major change in the FKF1- light-oxygen-voltage domain photoreaction.
Title: Kinetics of conformational changes of the FKF1-LOV domain upon photoexcitation.

ZTL, FKF1, and LKP2 together regulate TOC1 and PRR5 degradation and are major contributors to determining the period of circadian oscillation and enhancing robustness.
Title: F-box proteins FKF1 and LKP2 act in concert with ZEITLUPE to control Arabidopsis clock progression.

regulate gene expression of CO gene in arabidopsis.
