The complete mitochondrial genome of the hybrid grouper ♀ ♂ is presented in this study. The mitochondrial genome is 16,458bp long and consists of 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes and a control region. The gene order and composition of the hybrid grouper mitochondrial genome was similar to that of most other vertebrates. The nucleotide compositions of the light strand in descending order is 28.87% of G, 28.26% of T, 26.58% of A and 15.79% of C. With the exception of the NADH dehydrogenase subunit 6 (ND6) and eight tRNA genes, all other mitochondrial genes are encoded on the heavy strand. The phylogenetic analysis by maximum-likelihood (ML) method showed that the hybrid grouper has the closer relationship to the hybrid grouper ♀ × ♂.
本研究展示了杂交石斑鱼♀♂的完整线粒体基因组。线粒体基因组长度为16458bp，由13个蛋白质编码基因、2个rRNA基因、22个tRNA基因和一个控制区组成。杂交石斑鱼线粒体基因组的基因顺序和组成与大多数其他脊椎动物相似。轻链的核苷酸组成按降序排列为：鸟嘌呤（G）28.87%、胸腺嘧啶（T）28.26%、腺嘌呤（A）26.58%、胞嘧啶（C）15.79%。除了NADH脱氢酶亚基6（ND6）和8个tRNA基因外，所有其他线粒体基因都在重链上编码。通过最大似然法（ML）进行的系统发育分析表明，杂交石斑鱼与杂交石斑鱼♀×♂的关系更为密切。
