- Intervention effect Intermittent cold treatments trigger degradation of CONSTANS (CO) in Arabidopsis.
- Intervention effect Daily cold treatments suppress FLOWERING LOCUS T (FT) in Arabidopsis.
- Intervention effect Daily cold treatments delay flowering in Arabidopsis.
- Mechanism Cold-induced CO degradation is mediated by a ubiquitin/proteasome pathway involving the E3 ligase HOS1.
- Mechanism HOS1-mediated CO degradation occurs independently of the cold response pathways.
- Mechanism CO serves as a molecular hub integrating photoperiodic and cold stress signals into the flowering pathways.
- Mechanism The HOS1-CO module is proposed to fine-tune photoperiodic flowering under short-term temperature fluctuations.
