摘　　要： 中国水仙系石蒜科水仙属多年生草本植物.其花枝多,花香浓郁,素有"凌波仙子"的美称.但水仙花色单一,影响其观赏价值.花色形成与植物体内的一类次级代谢产物类黄酮有关. Chalcone synthase (CHS) is a key enzyme in the biosynthesis of all classes of flavonoids. The production of flower pigment is specifically regulated by the activity of CHS. We cloned the cDNA sequence of CHS-A gene from Narcissus by PCR and analyzed the coding sequence of gene. The result demonstrated that the sequence of the coding region was 1167bp, encoding a protein of 389 amino acid which was more than 80% homology with CHS of the other 8 plants, such as Nicotine abacus and Solaria tuberosum .
