VERNALIZATION1 (VRN1) is a multidomain DNA binding protein from Arabidopsis thaliana that is required for the acceleration of flowering time in response to prolonged cold treatment; a physiological process called vernalization. VRN1 is a 39 kDa protein comprised of two B3 domains flanking a putative nuclear localization sequence and two PEST domains. Here we report the (1)H, (13)C and (15)N resonance assignments of the 134 residue C-terminal region of VRN1, comprising a B3 DNA binding domain of the REM family and an upstream region that is highly conserved among VRN1 homologs from other dicotyledonous plant species.
