Abstract
Ctenophores are one of the most basally branching lineages of metazoans with the largest mitochondrial organelles in the animal kingdom. We sequenced the mitochondrial (mtDNA) genome from the Pacific cidipid ctenophore, Pleurobrachia bachei. The circular mitochondrial genome is 11,016 nts, with only 12 genes, and one of the smallest metazoan mtDNA genomes recorded. The protein coding genes are intronless cox1-3, cob, nad1, 3, 4, 4L and 5. The nad2 and 6 genes are represented as short fragments whereas the atp6 gene was found in the nuclear genome. Only the large ribosomal RNA subunit and two tRNAs were present with possibly the small subunit unidentifiable due to extensive fragmentation. The observed unique features of this mitochondrial genome suggest that nuclear and mitochondrial genomes have evolved at very different rates. This reduced mtDNA genome sharply contrasts with the very large sizes of mtDNA found in other basal metazoans including Porifera (sponges), and Placozoa (Trichoplax).
摘要
栉水母是后生动物中最基础的分支之一，拥有动物界中最大的线粒体器官。我们从太平洋栉水母 Pleurobrachia bachei 中测序了线粒体（mtDNA）基因组。这个圆形的线粒体基因组有 11016 个核苷酸，只有 12 个基因，是记录到的最小的后生动物 mtDNA 基因组之一。蛋白质编码基因无内含子 cox1-3、 cob、nad1、3、4、4L 和 5。nad2 和 6 基因以短片段的形式存在，而 atp6 基因存在于核基因组中。只有大亚基核糖体 RNA 和两个 tRNA 存在，由于广泛的碎片化，可能无法识别小亚基。这个线粒体基因组的独特特征表明，核基因组和线粒体基因组的进化速度非常不同。这种减少的 mtDNA 基因组与在其他基础后生动物中发现的非常大的 mtDNA 形成鲜明对比，包括多孔动物门（海绵）和扁盘动物门（栉水母）。
