Abstract

Whole mitochondrial DNA (mtDNA) of S.esocinusand S. plagiostomus was found to be 16,591 and 16,564 bp respectively with 13 protein-coding genes, 2 rRNAs genes, 22 tRNA genes and 2 non-coding region. For valuing the phylogenetic relationship of a species on the basis of whole mitogenome are considered to be a great importance. In this study, we sequenced whole mitogenome of S.esocinusand S. plagiostomus and compared with the whole mitogenome sequences of members of other families (Balitoridae, Nemanchillidae and Cobatidae). The monophyly of the family Cyprinidae and a clade comprising Balitoridae and Nemanchillidae while Cobatidae with paraphyletic origin was strongly supported by the resultant phylogenies, recognized that Cyprinidae was closely related with the family Cobatidae than other ones. The results indicated that whole mitochondrial genome has a great importance in studying variation in genes and phylogenetic relationship in the subfamily Schizothoracinae. This data offering the molecular phylogenetic frame work of important Schizothorax species found in Swat.

摘要

的全线粒体DNA（mtDNA）S.esocinus和S. plagiostomus被发现是16591并分别与13个蛋白质编码基因，2个rRNA基因，22个tRNA基因和2个非编码区16564碱基对。在整个有丝分裂基因组的基础上评估物种的系统发育关系被认为是非常重要的。在这项研究中，我们测序了S.esocinus和S. plagiostomus的整个有丝分裂基因组。并与其他家族成员（Balitoridae，Nemanchillidae和Cobatidae）的整个有丝分裂基因序列进行比较。Cyprinidae家族的一面目以及一个由Balitoridae和Nemanchillidae组成的进化枝，而具有近亲起源的Cobatidae则得到了由此形成的系统进化论的大力支持，他们认识到Cyprinidae与Cobatidae家族的亲缘关系比其他家族密切。结果表明，整个线粒体基因组在研究裂殖壶菌亚科的基因变异和系统发育关系方面具有重要意义。该数据提供了特警中发现的重要裂殖壶菌属物种的分子系统发育框架。
