摘要: 目的:探讨貂组织线粒体DNA(mtDNA)及细胞色素b(Cytb)的特征。方法:采用碱变性方法提取新鲜的貂心及肝组织中mtDNA,PCR技术扩增细胞色素b(Cytb)基因部分序列片段并直接测序。结果:新鲜的貂心和肝组织提取出16 800 bp的mtDNA,并能扩增出310 bp大小的Cytb基因,测序结果显示貂心Cytb基因与美洲貂(GenBank AB026109.1)同源性为99%。 结论:貂组织含有完整的mtDNA,Cytb部分基因可以作为貂心物种鉴定及检测的分子标记。

Abstract: Abstract:Objective To explore the characterization of mitochondrial DNA and cytochrome b (Cytb) gene from Martes zibellina L..Methods The mtDNA were extracted from fresh heart and liver of Martes zibellina L. by alkaline lysis method respectively, and Cyt b gene segment was amplified by PCR technique and sequenced. Results The  complete 16800 bp mtDNA was separated from both samples, and the Cytb gene with 310 bp segments was amplified by PCR and the sequence indicated that the homologous similarity was 99% with sable Martes zibellina L.(GenBank: AB026109.1) and it was 45% with other animal similarity.Conclusion There is complete mtDNA in tissues of Martes zibellina L. and Cytb partial gene from martes zibellina L.may be used as the genetic marker for identification of different species.

Key words: DNA, mitochondrial, cytochrome b
