Chimeric chalcone synthase
WebApr 27, 2009 · This phenomenon was originally described in transgenic petunia in which expression of the chalcone synthase-A(CHS-A) gene, required for the biosynthesis of anthocyanin pigments in the flower, was inhibited by the overexpression of a homologous sense transgene (Napoli et al. 1990). WebIn the chalcone synthase gene of Antirrhinum majus (snapdragon), 150 base pairs of the 5' flanking region contain cis-acting signals for UV light-induced expression. A nuclear factor, designated CG-1, specifically recognizes a hexameric motif with internal dyad symmetry, CACGTG, located within this light-responsive sequence.
