Multiple Roles of Arabidopsis VRN1 in Vernalization and Flowering Time Control
Copyright policy )Multiple Roles of Arabidopsis VRN1 in Vernalization and Flowering Time Control
Arabidopsis VRN genes mediate vernalization, the process by which a long period of cold induces a mitotically stable state that leads to accelerated flowering during later development. VRN1 encodes a protein that binds DNA in vitro in a non–sequence-specific manner and functions in stable repression of the major target of the vernalization pathway, the floral repressor FLC . Overexpression of VRN1 reveals a vernalization-independent function for VRN1 , mediated predominantly through the floral pathway integrator FT , and demonstrates that VRN1 requires vernalization-specific factors to target FLC .
