The complete mitochondrial genome of the hybrid grouper × is presented in this study. The mitochondrial genome is 16,418 bp 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 were similar to that of most other vertebrates. The nucleotide compositions of the light strand in descending order was 28.86% of G, 28.61% of T, 26.46% of A and 16.08% 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 shows that the hybrid grouper has closer relationship to and .
本研究报道了杂交石斑鱼×的完整线粒体基因组。线粒体基因组长度为16418bp，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：G占28.86%、T占28.61%、A占26.46%、C占16.08%。除NADH脱氢酶亚基6（ND6）和8个tRNA基因外，所有其他线粒体基因均由重链编码。通过最大似然（ML）法进行的系统发育分析表明，杂交石斑鱼与和的关系更近。
