Abstract

The complete mitochondrial genome of storhinchus was first presented in this study. The full length of the mitochondrial genome was 16,779 bp, including 13 protein-coding genes (PCGs), two ribosomal RNAs, 22 transfer RNA genes, a non-coding control region (CR) and one origin of replication on the light-strand (OL). The total nucleotide composition of mitochondrial DNA was 26.0% A, 30.2% C, 26.2% T and 17.5% G. 12 PCGs used the canonical ATG as their initiation codon, whereas COI gene started with an alternative start codon GTG. The mitochondrial genome of described in this study could be a useful basis for the management of this species and laid a foundation for further research involved with phylogenetic relationship within Apogoninae.

摘要

本研究首次公布了细纹天竺鲷的完整线粒体基因组。线粒体基因组全长16779 bp,包括13个蛋白质编码基因(PCGs)、两个核糖体RNA、22个转运RNA基因、一个非编码控制区(CR)和轻链上的一个复制起点(OL)。线粒体DNA的总核苷酸组成为:A占26.0%、C占30.2%、T占26.2%、G占17.5%。12个PCGs以典型的ATG作为起始密码子,而COI基因以替代起始密码子GTG开始。本研究中描述的 的线粒体基因组可能是该物种管理的有用基础,并为进一步研究天竺鲷亚科内的系统发育关系奠定了基础。
