Abstract

Omosita colon (Linnaeus, 1758) (Coleoptera: Nitidulidae) is an economically important storage pest worldwide and a forensically important beetle. The first complete mitochondrial genome (mitogenome) of O. colon was sequenced in this study using the next-generation sequencing. The mitogenome of O. colon is circular with a total length of 16,544 bp, which consists of 13 protein-coding genes, 22 transfer RNA genes, two ribosomal RNA genes, and a non-coding control region. The order and orientation of genes were identical with that of the ancestral insects. This study provides genomic data for mitogenome library of the genus Omosita to investigate evolutionary and systematic studies. It also provides a molecular basis to infer the postmortem interval (PMI_min) with O. colon.

摘要

Omosita结肠（Linnaeus，1758年）（鞘翅目：Nitidulidae）是一种在世界范围内具有重要经济意义的贮藏害虫，也是具有法医学意义的甲虫。在这项研究中，使用下一代测序技术对大肠结肠菌的第一个完整的线粒体基因组（有丝分裂基因组）进行了测序。的线粒体基因O.结肠是圆形的，具有16544个碱基的总长度，它由13个蛋白质编码基因，22个转移RNA基因中，两个核糖体RNA基因和非编码控制区。基因的顺序和方向与祖传昆虫的顺序和方向相同。这项研究为Omosita属的有丝分裂基因组文库提供了基因组数据调查进化和系统研究。它也提供了一个分子基础来推断O.结肠的死后间隔（PMI _min）。
