In this study, we first determined and described the complete mitogenome sequence of Parastichopus californicus, which was 16 727 bp in length. The mitochondrial genome had the canonical mitochondrial gene content, including 13 protein-coding genes, 2 rRNA genes and 22 tRNA genes. The overall base composition of the heavy-strand was 31.5% A, 18 % G, 20.6% C and 29.9% T, with a high A + T content of 61.4%. ML phylogenetic tree indicated that P. californicus and P. nigripunctatus were clustered in one branch belonging to the genus Parastichopus. This conclusion was identical to the former result by the methods of morphological taxonomy.
在本研究中，我们首先测定并描述了加州拟刺参的完整线粒体基因组序列，其长度为16727bp。线粒体基因组具有典型的线粒体基因组成，包括13个蛋白质编码基因、2个rRNA基因和22个tRNA基因。重链的总体碱基组成为31.5%A、18%G、20.6%C和29.9%T，A+T含量较高，为61.4%。最大似然法系统发育树表明，加州拟刺参和黑点拟刺参聚在属于拟刺参属的一个分支中。这一结论与形态分类学方法的先前结果一致。
