Abstract
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
.
