摘要: 本研究利用Y染色体AMELY基因分析中国马鹿的遗传多样性,对塔河马鹿、伊河马鹿、阿尔泰马鹿、东北马鹿、甘肃马鹿共200个个体的AMELY基因片段测序,分析马鹿Y染色体的单倍型多样性,通过构建系统进化树,研究中国马鹿的群体遗传多样性并对马鹿的父系起源进行探讨。结果显示:塔河马鹿变异位点最多,具有很高的核苷酸多样性,与其他马鹿间的遗传距离远;本试验共定义了6个单倍型,分别为A1、A2、A3、A4、A5、A6,其中塔河马鹿、阿尔泰马鹿和甘肃马鹿具有独有的单倍型;利用所获得AMELY基因序列,构建NJ和ML系统进化树发现:塔河马鹿自成一个单系;甘肃马鹿自成一个单系,伊河马鹿、阿尔泰马鹿、甘肃马鹿、东北马鹿聚成一类,阿尔泰马鹿、塔河马鹿、东北马鹿聚成一类,塔河马鹿、甘肃马鹿与其他马鹿之间可能存在基因交流。

Abstract: In order to determine the genetic diversity in Cervus elaphus using AMELY gene in Y chromosome,200 blood samples from Cervus elaphus yarkandensis,Cervus elaphus asiaticus,Cervus elaphus xanthopygus,Cervus elaphus songaricus and Cervus elaphus kansuensis populations were collected and AMELY genes were sequenced in this study.The haplotype diversity of Y chromosome was analyed,phylogenetic tree was built to explore the genetic diversity and the paternal origins about Cervus elaphus.The results showed that:Cervus elaphus yarkandensis had the most variation sites and the highest nucleotide diversity.The genetic distance between Cervus elaphus yarkandensis and other Cervus elaphus were far.6 haplotypes were identified in this study,named as A1,A2,A3,A4,A5 and A6,respectively.Cervu elaphus yarkandensis,Cervus elaphus asiaticus and Cervus elaphus kansuensis had separate haplotype.The NJ and ML phylogenetic trees showed that Cervus elaphus songaricus,Cervus elaphus asiaticus,Cervus elaphus xanthopygus and Cervus elaphus kansuensis clustered together which Cervus elaphus yarkandensis and Cervus elaphus kansuensis were form a department,separately.Cervus elaphus asiaticus,Cervus elaphus xanthopygus and Cervus elaphus yarkandensis clustered into one branches and there might be gene exchange among Cervus elaphus yarkandensis,Cervus elaphus kansuensis and other Cervus elaphus.

Key words: Cervus elaphus; Y chromosome; AMELY gene; paternal origins
