الوصف: For many plant species, reproductive success relies on the proper timing of flowering, and photoperiod provides a key environmental input. Photoperiod-dependent flowering depends on timely expression of FLOWERING LOCUS T (FT); however, the coordination of various cis-regulatory elements in the FT promoter is not well understood. Here, we provide evidence that long-distance chromatin loops bring distal enhancer elements into close association with the proximal promoter elements bound by CONSTANS (CO). Additionally, we show that NUCLEAR FACTOR Y (NF-Y) binds a CCAAT box in the distal enhancer element and that CCAAT disruption dramatically reduces FT promoter activity. Thus, we propose the recruitment model of photoperiod-dependent flowering where NF-Y complexes, bound at the FT distal enhancer element, help recruit CO to proximal cis-regulatory elements and initiate the transition to reproductive growth.
