The first complete mitochondrial (mt) genome of is reported herein, the gene composition and arrangement in mitogenome were identical to those of most vertebrates, which is 16,508 bp in length and contains 13 PCGs, two rRNA genes (12S rRNA and 16S rRNA), 22 tRNA genes, and a putative control region (CR) and one origin of replication on the light-strand (OL). Two start codon patterns and three stop codon patterns were found in protein-coding genes. Only the tRNA-Ser(AGY) could not fold into a typical clover-leaf secondary structure for lacking the dihydrouridine arm. A phylogenetic tree based on the neighbour-joining method was constructed to provide relationship within Beloniformes, which could be a useful basis for management of this species.
本文报道了首个完整的[物种名称]线粒体（mt）基因组，[物种名称]线粒体基因组中的基因组成和排列与大多数脊椎动物相同，其长度为16,508 bp，包含13个蛋白质编码基因（PCGs）、两个核糖体RNA基因（12S rRNA和16S rRNA）、22个转运RNA基因、一个假定的控制区（CR）以及轻链上的一个复制起点（OL）。在蛋白质编码基因中发现了两种起始密码子模式和三种终止密码子模式。只有tRNA-Ser(AGY)因缺少二氢尿嘧啶臂而无法折叠成典型的三叶草二级结构。基于邻接法构建了系统发育树，以揭示颌针鱼目内部的关系，这可为该物种的管理提供有用依据。
