Deciding When to Flower

Ruth Bastow and Caroline Dean

Plants must carefully time the switch from vegetative growth to floral production in order to take advantage of optimal environmental conditions. In their Perspective, Bastow and Dean discuss new work (He et al.) that reveals an elegant mechanism, involving chromatin remodeling of a genetic locus encoding a flowering repressor, which enables plants to regulate flowering time.
