| 摘 要： | 目的对长爪沙鼠线粒体ATPase8,ATPase6,COX3基因全序列进行测定,并对其进行鉴定及进化分析。方法根据长爪沙鼠已知基因序列设计引物,采用PCR产物测序法,对目的片段进行测序鉴定。结合已公布啮齿类动物ATPase8,ATPase6,COX3基因序列,分析其碱基组成、遗传距离、并基于最小进化法和UPGMA法构建系统进化树。结果获得长爪沙鼠线粒体ATPase8,ATPase6,COX3基因全序列,其与家鼠、小家鼠和仓鼠均具有较高的同源性(76～98%);进化分析结果显示,长爪沙鼠与家鼠、黑家鼠和仓鼠遗传距离较近;碱基G的含量分别为6.9%,10.7%,15.2%,符合mtDNA的特点;A+T含量分别为68.2%,64.1%,59.2%,明显低于G+C含量,符合哺乳动物的特点。结论本研究为首次获得长爪沙鼠ATPase8,ATPase6,COX3基因全序列,长爪沙鼠与家鼠、黑家鼠和仓鼠具有较近遗传距离,本研究为长爪沙鼠进化研究、线粒体的结构和功能研究奠定基础。
