Abstract

Solea ovata (Pleuronectiformes: Soleidae) is characterized by eyes on right side and an ovata body with small ctenoid scales on both sides. In this article, the complete mitogenome of Solea ovata was first determined. The total length is 16,782 bp, containing 13 protein-coding genes, 22 tRNA genes, and 2 rRNA genes (12S and 16S), as well as a putative control region and a L-strand replication origin (OL). Except eight tRNA and ND6 genes, all other mitochondrial genes are encoded on the heavy strand. Overall base composition is 29.2% A, 29.4% C, 15.9% G, and 25.5% T with a slight AT bias of 54.7%. The determination of S. ovata complete mitogenome could contribute to understanding the systematic evolution of the genus Solea and further phylogenetic study on Soleidae and Pleuronectiformes.

摘要

卵形鳎(鲽形目:鳎科)的特征是眼睛位于右侧,身体呈卵形,两侧有小栉鳞。在本文中,首次测定了卵形鳎的完整线粒体基因组。其全长为16,782 bp,包含13个蛋白质编码基因、22个tRNA基因和2个rRNA基因(12S和16S),以及一个假定的控制区和一个轻链复制起点(OL)。除了8个tRNA和ND6基因外,所有其他线粒体基因都在重链上编码。总体碱基组成为29.2%A、29.4%C、15.9%G和25.5%T,AT偏差率为54.7%。卵形鳎完整线粒体基因组的测定有助于了解鳎属的系统进化,并进一步开展鳎科和鲽形目的系统发育研究。
