Abstract

Abstract Turkey has a rich freshwater biodiversity in terms of Cyprinid genus in respect to its geographical location. To elucidate the phylogeny of the Alburnoides genus, one of these genera, genetic data for the cytochrome b gene (1141 bp) was generated for 445 samples collected at 42 sampling sites across their geographical distribution. A total of 54 mitochondrial haplotypes identified were distrubuted among distinct twelve species that did not share haplotypes with each other. Pairwise sequence divergence among these species range from 1.37% (A. emineae and A. velioglui) and 10.99% (A. manyasensis and A. smyrnae). A new potential species in the River Dirgine that run into the Black Sea Basin was separated from the most closed known species with mean 6.3%. Network analysis and phylogenetic analysis indicated that all haplotypes were clustered into two major clades, which corresponded to twenty-three Alburnoides lineages, with moderate-high bootstrap supports and mutational steps, respectively. Application of a molecular clock to a Bayesian phylogeny indicates that Alburnoides diversified under the paleogeographic conditions such as tectonic uplift and faulting Miocene aged as well as climatic oscillation and sea-level fluctuations during late Miocene-middle Pleistocene. The genetic results of the present study indicated the inter-specific distance of cyt b gene sequences followed the ideal results for species identification and phylogeny of Turkish spirlins.

基于线粒体DNA序列的土耳其Alburnoides属(Teleostei, Cyprinidae)的系统发育和系统地理学

土耳其就其地理位置而言，塞浦路斯属具有丰富的淡水生物多样性。为了阐明其中一个属Alburnoides属的系统发育，对分布在其地理分布的42个采样点的445个样本进行了细胞色素b基因(1141 bp)的遗传分析。共鉴定出54个线粒体单倍型，分布在12个不同的物种中，这些物种之间不具有相同的单倍型。两种间序列差异分别为1.37% (A. emineae和A. velioglui)和10.99% (A. manyasensis和A. smyrnae)。在汇入黑海盆地的Dirgine河中，一个新的潜在物种与最封闭的已知物种分开，平均为6.3%。网络分析和系统发育分析表明，所有单倍型聚为2大支系，分别对应23个桤木系，具有中高的引导支持和突变步长。分子钟对贝叶斯系统发育的应用表明，在中新世构造隆升和断裂等古地理条件下，以及中新世晚期-中更新世气候振荡和海平面波动等古地理条件下，Alburnoides具有多样性。本研究的遗传结果表明，cyt b基因序列的种间距离符合土耳其螺旋藻物种鉴定和系统发育的理想结果。

期刊介绍： Mitochondrial DNA Part A publishes original high-quality manuscripts on physical, chemical, and biochemical aspects of mtDNA and proteins involved in mtDNA metabolism, and/or interactions. Manuscripts on cytosolic and extracellular mtDNA, and on dysfunction caused by alterations in mtDNA integrity as well as methodological papers detailing novel approaches for mtDNA manipulation in vitro and in vivo are welcome. Descriptive papers on DNA sequences from mitochondrial genomes, and also analytical papers in the areas of population genetics, phylogenetics and human evolution that use mitochondrial DNA as a source of evidence for studies will be considered for publication. The Journal also considers manuscripts that examine population genetic and systematic theory that specifically address the use of mitochondrial DNA sequences, as well as papers that discuss the utility of mitochondrial DNA information in medical studies and in human evolutionary biology.
