Abstract

Sarcophila rasnitzyni Rohdendorf and Verves, 1985 (Diptera: Sarcophagidae) is of potential significance in medicine and epidemiology. In this study, we present the mitochondrial genome of S. rasnitzyni. The full length of the mitochondrial genome is 15,321 bp (GenBank accession no. MW592359), and 13 protein-coding genes (PCGs), two ribosomal RNAs (rRNAs), 22 transfer RNAs (tRNAs), and a non-coding control region were identified. Nucleotide composition is A 38.0%, G 9.9%, C 14.9%, T 37.2%, respectively. It reveals a strong A + T bias (75.2%). Phylogenetic analysis indicates that the species-level relationship between S. rasnitzyni and S. mongolica closely clusters together, and separates clearly from the rest of species. This study provides important genetic data for further enriching our understanding of phylogenetic relationship of sarcophagids species.

摘要

Sarcophila rasnitzyni Rohdendorf 和 Verves，1985（双翅目：Sarcophagidae）在医学和流行病学中具有潜在的意义。在这项研究中，我们展示了S. rasnitzyni的线粒体基因组。线粒体基因组全长为 15,321 bp（GenBank 登录号 MW592359），13 个蛋白质编码基因（PCG）、2 个核糖体 RNA（rRNA）、22 个转移 RNA（tRNA）和一个非编码控制区确定。核苷酸组成分别为 A 38.0%、G 9.9%、C 14.9%、T 37.2%。它揭示了强烈的 A + T 偏差（75.2%）。系统发育分析表明S. rasnitzyni与S. mongolica之间存在种级关系紧密地聚集在一起，并与其他物种明显分开。本研究为进一步丰富我们对石棺物种系统发育关系的理解提供了重要的遗传数据。
