The cen gene of Antirrhinum has been cloned, also homologues from Arabidopsis (tfl1) and rice. Flowering characteristics of transgenic plants, especially switching of apical meristem to a floral fate and the ting of flowering, may be manipulated by regulating gene expression. The promoter of the cen gene may be used to drive tissue-specific expression, specifically in the apical meristem of plants.
