The cen gene of Antirrhinum has been cloned, also homologues from Ara-bidopsis (tfl1) and rice. Flowering char-acteristics of transgenic plants, espe-cially switching of apical meristem to a floral fate and the timing of flower-ing, 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.

On a réalisé le clonage du gène cen d'Antirrhinum ainsi que d'homologues d'Arabidopsis (tfl1) et du riz. Les caractéristiques de floraison de plantes transgéniques, notamment le passage du méristème apical au devenir floral et le moment de la floraison, peuvent être manipulées par régulation de l'expression génique. Le promoteur du gène cen peut être utilisé pour induire une expression propre à un tissu, spécifiquement dans le méristème apical des plantes.
