Abstract

The starry flounder (Platichthys stellatus) and the spotted halibut (Verasper variegatus) are economically important flatfish species in Korea. The hybrid P. stellatus (♀) × V. variegatus (♂) has attracted attention in aquaculture. In this study, we report the first complete mitochondrial genome sequence of this hybrid flatfish, obtained using next-generation sequencing. The mitogenome is 16,874 bp in length and comprises 13 protein-coding genes, 22 tRNAs, and two rRNAs. Phylogenetic analysis revealed that the hybrid clusters with its maternal species, P. stellatus, confirming strict maternal inheritance of mitochondrial DNA. These findings provide genomic resources for phylogenetics and hybrid flatfish breeding.

杂交牙鲆鲽（♀）×斑牙鲆（♂）线粒体全基因组的研究。

星形比目鱼（Platichthys stellatus）和斑点比目鱼（Verasper variegatus）是韩国经济上重要的比目鱼品种。杂交体stellatus（♀）× V. variegatus（♂）在水产养殖中引起了广泛关注。在这项研究中，我们报告了这种杂交比目鱼的第一个完整的线粒体基因组序列，使用下一代测序获得。有丝分裂基因组全长16874 bp，由13个蛋白质编码基因、22个trna和2个rrna组成。系统发育分析表明，该杂种群与其母系种P. stellatus具有严格的母系线粒体DNA遗传。这些发现为比目鱼的系统发育和杂交育种提供了基因组资源。
