The complete mitogenome of the hexacorallia, has been amplified and sequenced. The mitogenome consists of 17,886 bp, with 13 protein-coding genes, 2 ribosomal RNA genes, 2 transfer RNA genes and a control region. It has been observed that ND5 gene is split into two parts by a large fragment of genes, which commonly presented in scleractinian coral. The overall base composition of the H-strand was A, 24.91%; G, 24.1%; C, 14.2%; and T, 36.8%, with a slight AT bias of 61.7%. The control region was 627 bp in length and located between 12S rRNA and COIII gene. Based on the neighbour-joining (NJ) tree, was grouped with , and , and formed a clade of Acroporidae. In conclusion, the complete mitogenome of data may provide more informative for phylogenetic approach for corals phylogeny.
六放珊瑚的完整线粒体基因组已被扩增和测序。该线粒体基因组由17,886个碱基对组成,包含13个蛋白质编码基因、2个核糖体RNA基因、2个转运RNA基因和一个控制区。据观察,ND5基因被一大段基因分成两部分,这在石珊瑚中很常见。H链的总体碱基组成为:A占24.91%、G占24.1%、C占14.2%、T占36.8%,AT偏差率为61.7%,略呈AT偏向性。控制区长627个碱基对,位于12S rRNA和COIII基因之间。基于邻接法(NJ)树, 与 、 和 归为一组,并形成了鹿角珊瑚科的一个分支。总之, 数据的完整线粒体基因组可能为珊瑚系统发育的系统发育方法提供更多信息。
