Abstract：
:CONSTANS (CO) is a master regulator of flowering time, although the mechanisms underlying its role as a transcriptional regulator are not well understood. The DNA-binding domain of CO shares homology with that of NUCLEAR FACTOR YA (NF-YA), a subunit of the CCAAT-binding trimer NF-Y. Recent publications indicate that CO and its rice homolog HEADING DATE 1 (Hd1) form heterotrimers with the histone-fold subunits of NF-Y to efficiently bind promoter elements in the florigen genes. Differences in the DNA-binding specificities of NF-Y and NF-CO can be conceptualized based on our knowledge of the 3D structure of the NF-Y/CCAAT complex. Here we discuss the modes of assembly of NF-Y-like heterotrimers and possible models for their activity as flexible sequence-specific transcriptional regulators.
