Abstract:
Forty-five tick species have been recorded in Kazakhstan. However, their genetic diversity and evolutionary relationships, particularly when compared to ticks in neighbouring countries, remain unclear. In the present study, 148 mitochondrial cytochrome c oxidase subunit I (COI) sequence data from our laboratory and NCBI (National Center for Biotechnology Information; https://www.ncbi.nlm.nih.gov/ ) data were used to address this knowledge gap. Phylogenetic analyses showed that i) Hyalomma anatolicum anatolicum (Koch, 1844) ticks from Jambyl Oblast (southeastern Kazakhstan) and Gansu Province (northwestern China) constituted a newly deviated clade; and ii) Dermacentor reticulatus (Fabricius, 1974) ticks from South Kazakhstan Oblast were closer to those in Romania and Turkey. The network diagram of haplotypes showed that i) the H-1 and H-2 haplotypes of Dermacentor marginatus (Sulzer, 1776) ticks from Zhetisu and Almaty were all newly evolved; and ii) the H-3 haplotypes of Haemaphysalis erinacei (Pavesi, 1884) from Almaty Oblast and Xinjiang Uygur Autonomous Region (northwestern China) were evolved from the H-1 haplotype from Italy. In the future, more COI data from different tick species, especially from Kazakhstan and neighbouring countries, should be employed in the field of tick DNA barcoding.
摘要:
哈萨克斯坦已记录了45种tick虫。然而,它们的遗传多样性和进化关系,特别是与邻国的蜱虫相比,仍然不清楚。在本研究中,148线粒体细胞色素c氧化酶亚基I(COI)序列数据来自我们的实验室和NCBI(国家生物技术信息中心;https://www。ncbi.nlm.nih.gov/)数据被用来解决这一知识差距。系统发育分析表明,i)anatolicumanatolicum(Koch,1844)来自JambylOblast(哈萨克斯坦东南部)和甘肃省(中国西北部)的壁虱构成了一个新偏离的进化枝;和ii)Dermacentorreticulatus(Fabricius,1974)南哈萨克斯坦州的蜱虫更接近罗马尼亚和土耳其。单倍型的网络图表明,i)Dermacentormarginatus的H-1和H-2单倍型(Sulzer,1776)来自Zhetisu和阿拉木图的蜱都是新进化的;以及ii)红血丝的H-3单倍型(Pavesi,1884)来自阿拉木图州和新疆维吾尔自治区(中国西北部)的H-1单倍型来自意大利。在未来,来自不同蜱物种的更多COI数据,特别是来自哈萨克斯坦和邻国,应该用于蜱DNA条形码领域。
