摘要: 根据鸡、鸭等的IGF-Ⅰ基因5’调控区的保守区序列设计一对兼并引物,从五龙鹅的基因组DNA中扩增了IGF-Ⅰ基因5’调控区序列,将其克隆到pMD18-T载体上进行测序,结果得到长796 bp的序列。五龙鹅IGF-Ⅰ基因5’调控区序列与鸭、鸡的同源性分别为98.1%、93.0%,充分显示了IGF-Ⅰ基因在进化上的高保守性;与鸭相比有4处碱基缺失和7处碱基插入;与鸡相比有4处碱基缺失和3处碱基插入。对其序列进行酶切图谱分析发现,共有5种常见的限制性内切酶的酶切位点。

Abstract: According to the IGF-Ⅰgene 5’-UTR conserved sequences of chicken, duck etc, a pair of degenerate primer was designed to amplify the sequence of Wulong Goose IGF-Ⅰgene 5’-UTR from the genomic DNA. And then the PCR product was subcloned to the pMD18-T vector and sequenced which was 796 bp in length. Compared with the duck and chicken, Wulong Goose IGF-Ⅰgene 5’-UTR sequence shared 98.1%and 93.0%nucleotide homology respectively which indicated that IGF-Ⅰgenes were highly conservative in phylogeny. Moreover, it has 4 bases deletion and 7 bases insertion compared to duck, and 4 bases deletion and 3 bases insertion compared to chicken. There are 5 kind of common restriction sites through nuclear acid DNA sequence by macrorestriction map analyzing.
