The massive destruction and deterioration of the habitat of Oryx leucoryx and illegal hunting have decimated Oryx populations significantly, and now these animals are almost extinct in the wild. Molecular analyses can significantly contribute to captive breeding and reintroduction strategies for the conservation of this endangered animal. A representative 32 identical sequences used for species identification through BOLD and GenBank/NCBI showed maximum homology 96.06% with O. dammah, which is a species of Oryx from Northern Africa, the next closest species 94.33% was O. gazella, the African antelope. DNA barcode sequences of the mitochondrial cytochrome C oxidase (COI) gene were determined for O. leucoryx; identification through BOLD could only recognize the genus correctly, whereas the species could not be identified. This was due to a lack of sequence data for O. leucoryx on BOLD. Similarly, BLAST analysis of the NCBI data base also revealed no COI sequence data for the genus Oryx.
阿拉伯大羚羊栖息地的大规模破坏和退化以及非法捕猎,已使阿拉伯大羚羊种群数量大幅减少,如今这些动物在野外几乎灭绝。分子分析可为这种濒危动物的圈养繁殖和重新引入策略做出重大贡献。通过生命条形码数据系统(BOLD)和基因库/美国国立生物技术信息中心(GenBank/NCBI)用于物种鉴定的32个代表性相同序列显示,与来自北非的一种阿拉伯大羚羊——旋角羚的最大同源性为96.06%,第二接近的物种——非洲羚羊细角羚的同源性为94.33%。已测定了阿拉伯大羚羊线粒体细胞色素C氧化酶(COI)基因的DNA条形码序列;通过BOLD进行鉴定时只能正确识别其属,而无法识别其种。这是由于BOLD上缺乏阿拉伯大羚羊的序列数据。同样,对NCBI数据库的BLAST分析也显示,没有阿拉伯大羚羊属的COI序列数据。
