The present study was conducted to get more information about the genome and locate the taxonomic position of in Schizothoracinae through mitochondrial 13 protein-coding genes (PCGs). These PCGs for were found to be 11409 bps in length ranging from 165 (ATPase 8) to 1824 bps (NADH dehydrogenase subunit 5) and encode 3801 amino acids. In these PCGs, 4 genes overlap on the similar strands, while one shown on the opposite one: ATPase 6+8 and NADH dehydrogenase subunit 4+4L overlap by 7 nucleotides. Similarly, ND5-ND6 overlap by 4 nucleotides, while ATP6 and COIII overlap by 1 nucleotide. Similarly, four commonly used amino acids in were Leu (15.6 %), Ile (10.12 %), Thr (8.12 %), and Ala (8.7 %). The results presented that COII, COIII, NDI, ND4L, and Cytb had substantial amino acid conservation as compared to the COI gene. Through phylogenetic analysis, it was observed that is closely linked with , , , and with high bootstrap values. The present study provided more genomic data to know the diversity of the mitochondrial genome and its molecular evolution in Schizothoracinae.
本研究旨在通过线粒体 13 个蛋白编码基因(PCGs)获取更多关于 基因组和分类位置的信息。结果表明, 线粒体 PCGs 的长度为 11409bp,范围为 165(ATPase 8)至 1824bp(NADH 脱氢酶亚基 5),编码 3801 个氨基酸。在这些 PCGs 中,有 4 个基因在相似链上重叠,而 1 个基因在相反链上显示:ATPase 6+8 和 NADH 脱氢酶亚基 4+4L 重叠 7 个核苷酸。同样,ND5-ND6 重叠 4 个核苷酸,而 ATP6 和 COIII 重叠 1 个核苷酸。同样,亮氨酸(15.6%)、异亮氨酸(10.12%)、苏氨酸(8.12%)和丙氨酸(8.7%)是 中常用的 4 种氨基酸。结果表明,与 COI 基因相比,COII、COIII、NDI、ND4L 和 Cytb 具有更高的氨基酸保守性。通过系统发育分析,观察到 与 、 、 以及 密切相关,支持率较高。本研究提供了更多的基因组数据,以了解线粒体基因组的多样性及其在 Schizothoracinae 中的分子进化。
