FLOWERING GENES

摘要

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