This study reported the isolation and characterization of eight polymorphic microsatellite loci in endangered forest musk deer Moschus berezovskii. An improved enrichment protocol was used to isolate microsatellites, and polymorphism was explored with samples from wild musk deer population collected in Miyalo of Sichuan Province in China. Approximately 70% of clones from the genomic library constructed in current study contained dinucleotide (AC) repeats. Eight microsatellite loci amplified were highly polymorphic within forest musk deer population. The number of alleles per locus ranged from 6 to 14, and the observed and expected heterozygosities ranged from 0.41 approximately 1.0 and from 0.8 approximately 0.9, respectively. The average polymorphic information content (PIC) value for these markers was 0.82. This demonstrated that the eight microsatellite loci developed here are highly polymorphic, and can be used as genetic markers for further investigation of musk deer. Also, the results showed that the musk deer distributed in Miyalo had a relatively higher level of genetic variation.
本研究报道了濒危林麝Moschus berezovskii的8个多态性微卫星位点的分离与特征分析。采用改进的富集方案分离微卫星,并利用从中国四川省米亚罗采集的野生林麝种群样本探究其多态性。在本研究构建的基因组文库中,约70%的克隆含有二核苷酸(AC)重复序列。扩增得到的8个微卫星位点在林麝种群内具有高度多态性。每个位点的等位基因数在6至14个之间,观察杂合度和期望杂合度分别在约0.41至1.0和0.8至0.9之间。这些标记的平均多态信息含量(PIC)值为0.82。这表明在此开发的8个微卫星位点具有高度多态性,可作为遗传标记用于林麝的进一步研究。此外,结果表明分布在米亚罗的林麝具有相对较高水平的遗传变异。
