We described the complete mitochondrial genome of the Ctenophore , which is a circular molecule of 10,487 bp in length. The new mitochondrial genome comprised only 12 genes, making it one of the smallest animals' mtDNA. Both nucleotide substitution and gene order rearrangements exhibited extreme high evolutionary rate in mitogenomes of Ctenophore. The phylogenetic analysis based on mitogenomics failed to reveal the basal position of Ctenophore within metazoan, owing to the extreme evolutionary rate. Based on the available Ctenophora mitogenomes, we found the optimized primers designed by Geller et al. for DNA barcoding suited for the taxon.
我们描述了栉水母的完整线粒体基因组，它是一个长度为10487 bp的环状分子。新的线粒体基因组仅包含12个基因，使其成为动物线粒体DNA最小的之一。在栉水母的线粒体基因组中，核苷酸替换和基因顺序重排均表现出极高的进化速率。基于线粒体基因组学的系统发育分析未能揭示栉水母在后生动物中的基部位置，这是由于其极高的进化速率。基于现有的栉水母线粒体基因组，我们发现Geller等人设计的用于DNA条形码的优化引物适用于该分类单元。
