We report the entire mitochondrial genome of the scarce blue-tailed damselfly, Ischnura pumilio (Odonata, Coenagrionidae), using next-generation sequencing on genomic DNA. A de novo assembly provided a single contiguous sequence of 15,250 bp that contained the A + T-rich region and all standard coding regions; gene configuration is similar to other odonates and comprises 13 protein-coding genes, two rRNA genes (12 S and 16 S rRNA) and 22 tRNA genes. We found a unique intergenic spacer in I. pumilio and confirm that the intergenic spacer s5 likely represents a synapomorphy between Anisoptera and Zygoptera. This is the first mitogenome sequence obtained for a member of the Coenagrionidae and demonstrates how next-generation sequencing technology can obtain mtDNA genome sequences without prior sample processing or primer design.
我们利用基因组DNA的下一代测序技术,报道了珍稀蓝尾豆娘(Ischnura pumilio,蜻蜓目,色蟌科)的完整线粒体基因组。从头组装得到了一个15250 bp的连续序列,其中包含富含A+T的区域和所有标准编码区域;基因配置与其他蜻蜓目昆虫相似,包括13个蛋白质编码基因、两个rRNA基因(12 S和16 S rRNA)和22个tRNA基因。我们在蓝尾豆娘中发现了一个独特的基因间隔区,并证实基因间隔区s5可能代表了差翅亚目和均翅亚目之间的一个共衍征。这是首次获得色蟌科成员的线粒体基因组序列,并展示了下一代测序技术如何在无需事先样本处理或引物设计的情况下获得线粒体DNA基因组序列。
