Model for the Role of BAF60 in the Control of Flowering Time.

(A) Genetic model. Under LD conditions and after a vernalization treatment in wild-type plants, FLC is repressed by BAF60 to promote flowering. In BAF60 RNAi lines, a high level of FLC expression induces a repression of SOC1 and leads to a late-flowering phenotype.

(B) Molecular model. Under LD conditions in wild-type plants, an equilibrium exists between the formation and the release of the FLC loop in which BAF60 is involved. This equilibrium could be destabilized by the knockdown of BAF60.
