鹿类微卫星遗传标记的研究现状(英文)

微卫星DNA在染色体上随机即分布，是十分有效的遗传标记。目前，在鹿类发现约有200 多个微卫星位点，除了极少数位点是直接从DNA文库中筛选的以外，绝大多数都是将牛、羊 的微卫星位点“借用”到鹿类。这些位点被广泛应用到父权鉴定、遗传多样性和种群结构分 析、种群基因渗入的检测、孕期长短及越冬存活率等的遗传标记等方面的研究中。然而，微 卫星DNA的数量目前还远不能满足研究需要。将来要在以下方面开展工作：1）分离更多的鹿 类特异的微卫星位点，2）构建微卫星位点的遗传和物理图谱。这样，微卫星DNA才能在鹿类 研究中发挥更大的作用。

Status of microsatellites as genetic markers in cervids

Microsatellite loci distributing on genome randomly act as effective genetic markers. To date, about 200 microsatellite loci were found in cervids b y transferring microsatellite PCR primers derived in bovine, ovine to cervids, a s well as a few loci derived directly from deer microsatellite library. These lo ci have been used in parentage determination, genetic diversity and population s tructure, population introgression, as genetic marker gestation length and winte ring survival et al. However, microsatellite loci presently found are untouchabl e to the demand of application. Future work should include: 1) isolating a large number of cervine microsatellite loci, 2) constructing genetic and physical map s of microsatellite loci. So that microsatelites have a strong base for advanced applications in deer.
