New cDNA sequences for chalcone synthase (CHS), a key enzyme in the flavonoid biosynthesis, were obtained from the Japanese and common morning glories; they are more closely related to other CHS sequences than the six previously described CHS genes from the same plants. The newly isolated CHS-D gene is abundantly expressed in the pigmented flower buds, while its expression is drastically reduced in the white flower buds. Thus CHS-D appears to produce major CHS transcripts for flower pigmentation.
从日本牵牛花和普通牵牛花中获得了查尔酮合酶（CHS）的新cDNA序列，查尔酮合酶是类黄酮生物合成中的关键酶；与之前从同一植物中描述的六个CHS基因相比，它们与其他CHS序列的关系更为密切。新分离的CHS-D基因在有色素的花芽中大量表达，而在白色花芽中的表达则急剧减少。因此，CHS-D似乎产生了用于花色素沉着的主要CHS转录本。
