摘要： 查尔酮合成酶（chalcone synthase， CHS)是黄酮类物质合成的第一关键酶。为了获得CHS基因，我们在 ACGM标记所扩增的PCR片段内设计锚定引物，并结合RACE技术首次克隆了柳杉属3种植物的CHS基因，包括柳杉（Cryptomeria japonica var. sinensis， CjsCHS）、短茸柳杉（C. japonica cv. Araucarioides，CjaCHS）和日本柳杉（C. japonica，CjCHS），并对其进行分析。结果表明:3个基因长都为1176 bp，编码391个氨基酸，它们都含有CHS高度保守活性位点以及CHS标签序列GFGPG，其编码蛋白的相似度达99%,与其他植物相似度在 79%以上,表明CHS基因在进化上具有相对保守性。
Abstract: Chalcone synthase (CHS) is the first enzyme in the flavonoid biosynthetic pathway in plants. In order to clone CHS gene in Cryptomeria plants, the amplified consensus genetic markers (ACGM) were designed and combined with RACE technique, three CHS genes in Cryptomeria japonica var. sinensis，C. japonica cv. Araucarioides and C. japonica were obtained, respectively. Sequence analysis showed that the coding sequence (CDS) of each CHS gene was 1176 bp in length and encoded 391 amino acids. The GFGPG tag of CHS conservative active sites were found in their proteins. Three CHS proteins showed 99% homology with each other, but more than 79% homology with other plants, which indicated that CHS were  relatively conserved during evolution.
