We present the mitochondrial genome of the deep-sea, epibenthic, irregular echinoid , representing the first sequenced mitogenome of the order Holasteroida. The length of the complete mitochondrial genome is 15,716 base pairs, and its GC content is 34.87%. It contains 13 protein-coding genes, two rRNA genes, and 22 tRNA genes, whose order is identical to that of all other available echinoid mitogenomes. Phylogenetic analysis of available mitochondrial genomes, based on all coding loci, places as the sister group to spatangoids (heart urchins).
我们展示了深海、底栖、不规则海胆的线粒体基因组，这是全星海胆目首个测序的有丝分裂基因组。完整线粒体基因组的长度为15,716个碱基对，其GC含量为34.87%。它包含13个蛋白质编码基因、两个rRNA基因和22个tRNA基因，其排列顺序与所有其他已有的海胆有丝分裂基因组相同。基于所有编码位点对现有线粒体基因组进行的系统发育分析表明，它是心形海胆（笋海胆）的姐妹群。
