  • 功能：
    Transcription factor that acts in the long day flowering pathway and may mediate between the circadian clock and the control of flowering. Plays a role in the regulation of flowering time by acting on 'SUPPRESSOR OF OVEREXPRESSION OF CO1', 'TERMINAL FLOWER 1' and 'FLOWERING LOCUS T'. Also regulates P5CS2 and ACS10 (involved in proline and ethylene biosynthesis, respectively). Regulates the expression of NAKR1 by binding to the 5'-TGTG(N2-3)ATG-3' motif.
  • 基因功能参考文献：
    1. The clock-controlled mechanism by which photoperiodic information regulates CONSTANS function is the key mechanism in Arabidopsis. PMID: 27688622
    2. A heavy-metal-associated (HMA) domain-containing protein, SODIUM POTASSIUM ROOT DEFECTIVE 1 (NaKR1), is activated by CONSTANS (CO) under long-day conditions and regulates long-distance movement of FT in Arabidopsis. Loss of function of NaKR1 compromises FT transport to shoot apices through sieve elements, causing late flowering under long-day conditions. PMID: 27255839
    3. CO expression during night time temperatures and flowering PMID: 26856528
    4. Data indicate that CONSTANS (CO) plays an active role in sustaining its diurnal accumulation dynamics during Arabidopsis photoperiodic flowering. PMID: 27607358
    5. Results indicate that the DELLA-CONSTANS (CO) cascade inhibits CO/FLOWERING LOCUS T (FT)-mediated flowering under LDs, which thus provide evidence to directly integrate gibberellin (GA) and photoperiod signaling to synergistically modulate flowering under long days (LDs). PMID: 27406167
    6. PRR-mediated stabilization increases binding of CO to the promoter of FLOWERING LOCUS T (FT), leading to enhanced FT transcription and early flowering under these conditions. PMID: 28270524
    7. CO protein phosphorylation contributes to the photoperiodic flowering response by enhancing the rate of CO turnover via activity of the COP1 ubiquitin ligase. PMID: 26358558
    8. Interaction of CO with miP1a/b/TPL causes late flowering due to a failure in the induction of FLOWERING LOCUS T (FT) expression under inductive long day conditions. PMID: 27015278
    9. these findings suggest that regulation of flowering by gibberellin (GA) signaling in leaves under long days is mediated through repression of DELLA proteins on CO, providing a molecular link between DELLA proteins, key components in GA signaling pathway, and CO, a critical flowering activator in photoperiod signaling pathway. PMID: 26801684
    10. Red light-mediated degradation of CO protein by HOS1 ligase regulates photoperiodic flowering in Arabidopsis. PMID: 26373454
    11. BBX19 as a circadian clock output that depletes the active CO pool to accurately monitor daylength and precisely time FT expression. PMID: 25228341

    13. report that TARGET OF EAT1 (TOE1) and related proteins interact with the activation domain of CONSTANS (CO) and CO-like (COL) proteins and inhibit CO activity. PMID: 25934507
    14. PFT1 is an activator of CO transcription, and also of FT transcription, in a CO-independent manner. PFT1 acts as a hub, integrating a variety of interdependent environmental stimuli, including light quality and jasmonic acid-dependent defences. PMID: 21985558
    15. Photoperiodic flowering regulators CO and GI are involved in FT- and TSF-mediated stomatal opening induced by blue light. PMID: 23669744
    16. 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 PMID: 22628657
    17. Overexpression of all FBH genes drastically elevated CO levels and caused early flowering regardless of photoperiod, whereas CO levels were reduced in the fbh quadruple mutants. PMID: 22334645
    18. CONSTANS was found to bind DNA via a unique sequence element containing a consensus TGTG(N2-3)ATG motif present in tandem within the FLOWERING LOCUS T promoter. PMID: 20406410
    19. CONSTANS is repressed by the E3 ligase DAY NEUTRAL FLOWERING, which prevents early flowering in short days. PMID: 20435904
    20. CO-derived signal(s), or possibly CO itself, fits the definition of the hypothetical flowering stimulant, florigen. PMID: 15299137
    21. findings show that FKF1 controls daily CONSTANS expression in part by degrading CYCLING DOF FACTOR 1 (CDF1), a repressor of CONSTANS transcription PMID: 16002617
    22. Promotes flowering specifically under long days. PMID: 16006578

    25. COb was retained for a long period after duplication, but a recent fixation of a detrimental mutation, possibly as an effect of a bottleneck, resulted in its nonfunctionalization in brassica nigra. PMID: 17344804
