摘要: 目的 克隆东方田鼠长江亚种(Microtus fortis calamorum)和宁夏指名亚种(Microtus fortis fortis)Y染色体的部分序列,并挖掘这两个亚种间的单核苷酸多态性位点(SNPs)。方法 本研究利用依据Y染色体保守性靶标位点(YCATS)设计的引物,测得Y染色体上的8个内含子短片段序列,进而设计长片段PCR(LA-PCR)引物来获得相距几kb的两个内含子之间的长片段序列。结果 获得东方田鼠长江亚种和宁夏指名亚种Y染色体上的7300 bp序列,比对这两个亚种的序列后发现4个SNPs位点。结论 获得了田鼠Y染色体上的7 300 bp序列和4个SNPs位点。

Abstract: Objective To obtain the sequences of Y chromosome of Microtus fortis calamorum and Microtus fortis fortis, and find out some SNPs of these two subspecies. Methods Eight short segments' sequences involving in introns of ChrY are sequenced by using Y chromosome conserved anchored tagged primers, which would be used to design two new pairs of primers to achieve two long fragments of several kb in size through LA-PCR (Long and accurate polymerase chain reaction). Results About 7300 bp long on ChrY of M.f.calamorum and M.f.fortis is obtained respectively, for the first time, and 4 SNPs by comparing the sequences of these two subspecies are obtained. Conclusion The 7300 bp sequences on Y chr and 4 SNPs are obtained.

Key words: Microtus fortis, Single nuclear polymorphism (SNP), Y chromosome conserved anchored tagged sequences (YCATS), Long and accurate polymerase chain reaction (LA-PCR)
