Abstract

In this study, the complete mitochondrial genome of is presented, and we also discussed its mitochondrial characteristics. The full length of the mitochondrial genome was 16,847 bp, including 13 protein-coding genes (PCGs), 2 ribosomal RNAs, 22 transfer RNA genes, one non-coding control region (CR), and one origin of replication on the light-strand. The total nucleotide composition of the mitochondrial genome was 31.11% A, 24.62% T, 29.10% C, 15.16% G, and AT was 55.73%. The phylogenetic tree based on the ML method supported the placement of in a close relationship with These data contribute to a better understanding of the systematics of the Pristigasteridae.

摘要

在本研究中,呈现了[物种名称]的完整线粒体基因组,并讨论了其线粒体特征。线粒体基因组全长16,847 bp,包括13个蛋白质编码基因(PCGs)、2个核糖体RNA、22个转运RNA基因、1个非编码控制区(CR)和1个轻链复制起点。线粒体基因组的总核苷酸组成为:A占31.11%、T占24.62%、C占29.10%、G占15.16%,AT含量为55.73%。基于最大似然法(ML)构建的系统发育树支持[物种名称]与[另一物种名称]关系密切。这些数据有助于更好地理解锯腹鳓科的系统分类。
