This study reported the 15,435 bp-long complete mitochondrial genome of the relict Epiophlebia superstes (Odonata, Epiophlebiidae), an enigmatic dragonfly of the paraphyletic 'Anisozygoptera' possessing characteristics similar to members of both extant odonate suborders, the Zygoptera and the Anisoptera. This mitogenome comprises the common set of 37 genes and an A + T-rich control region, and has a gene arrangement identical to those of all available odonates. The genome contains three non-coding inter-genic spacers (s1-s3), which occurs in all of other known odonates, but it lacks the inter-genic spacer s5 typically found in the Anisoptera. This result suggests that E. superstes possesses a mitogenmic organization more closely related to that of the Zygoptera than that of the Anizoptera.
本研究报道了孑遗蜻蜓超级大蜓(蜻蜓目,大蜓科)长度为15435 bp的完整线粒体基因组,超级大蜓是并系“间翅亚目”中一种神秘的蜻蜓,具有与现存蜻蜓目两个亚目——均翅亚目和差翅亚目成员相似的特征。该线粒体基因组包含一套常见的37个基因和一个富含A+T的控制区,其基因排列与所有已有的蜻蜓目昆虫相同。该基因组包含三个非编码基因间隔区(s1 - s3),这在所有其他已知蜻蜓目昆虫中都存在,但缺少差翅亚目中通常发现的基因间隔区s5。这一结果表明,超级大蜓的线粒体基因组组织与均翅亚目的关系比与差翅亚目的关系更为密切。
