FLOWERING GENES

摘要

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.
