Objective The cytochrome C oxidase subunitⅠ(COⅠ) gene polymorphisms for Rattus norvegicus, was studied to provide support for the species identification of rodents from frontier port. Methods The COⅠ gene of R. norvegicus was amplified, sequenced, aligned and compared with the information on GenBank to analyze genetic polymorphism and create phylogenetic tree for R. norvegicus. Results Forty-eight COⅠ gene sequences were obtained from R. norvegicus. In this research, 605 loci were measured in each sequence, there were 587 conservative loci and 18 mutation loci, the nucleotide differences number was (2.510 000±0.000 640) on average. All of R. norvegicus in Jiangsu port background only shared one haploid type, other R. norvegicus' nucleotide polymorphism was rich. Conclusion There are species differences of the R. norvegicus in different areas, this kind of difference is related to the geographical origin.

目的 研究褐家鼠线粒体DNA细胞色素C氧化酶亚基Ⅰ(COⅠ)基因的遗传多态性特征,为国境口岸鼠形动物的鉴定和溯源提供技术支持。方法 通过对江苏口岸本底及输入性褐家鼠COⅠ基因的扩增、测序和比对,结合GenBank的褐家鼠信息,对褐家鼠进行遗传多态性分析和系统发育树研究。结果 获得48个国内外褐家鼠COⅠ基因序列,测出的605个序列位点中保守位点587个,可变异位点18个,核苷酸平均差异数为(2.510 000±0.000 640);江苏口岸本底褐家鼠仅为1个单倍型,非江苏口岸褐家鼠多态性丰富。结论 不同地区的褐家鼠具有一定的种内差异,该差异与地理位置分布有一定的关系。
