Abstract

In this study, we announce the complete mitochondrial genome (mitogenome) of the Korean endemic firefly, Luciola unmunsana Doi, 1931. The full-length circular genome was 15,858 bp, with 77.94% A/T content. It contained the typical set of 37 metazoan genes: 13 protein-coding genes (PCGs), 22 transfer RNA (tRNA) genes, and 2 ribosomal RNA (rRNA) genes, as well as an A + T-rich region. The gene arrangement of the species is identical to that of the ancestral arrangement found in the majority of insects. The maximum-likelihood tree, built using all PCGs and two rRNAs via randomized accelerated maximum likelihood (RAxML) showed that L. unmunsana was grouped as a sister to L. curtithorax with the highest nodal support. However, another Luciola species clustered with the Aquatica species such that the genus Luciola was a non-monophyletic group. Therefore, more sampling is required to clarify the phylogeny of Luciola.

摘要

在这项研究中，我们宣布了韩国地方性萤火虫Luciola unmunsana Doi，1931年的完整线粒体基因组（有丝分裂基因组）。全长环状基因组为15858 bp，A / T含量为77.94％。它包含一组典型的37个后生动物基因：13个蛋白质编码基因（PCG），22个转移RNA（tRNA）基因和2个核糖体RNA（rRNA）基因，以及富含A + T的区域。该物种的基因安排与大多数昆虫中的祖先安排相同。最大似然树，使用所有的PCG，并通过显示随机加速最大似然（RAxML）两大rRNA的内置L. unmunsana被编组为妹妹L. curtithorax最高的节点支持。但是，另一个Luciola物种与Aquatica物种聚集在一起，因此Luciola属是非单性群体。因此，需要更多的采样来阐明Luciola的系统发育。
