Abstract

Monomorium is one of the most species-rich yet taxonomically problematic ant genus. An East Asian species, M. triviale Wheeler, W.M., 1906, is reproduced by obligate thelytokous parthenogenesis and performs strict reproductive division of labor. We sequenced the M. triviale mitogenome using next-generation sequencing methods. The circular mitogenome of M. triviale was 16,290 bp in length, consisting of 13 protein-coding genes, two ribosomal RNA genes, 22 transfer RNAs, and a single non-coding region of 568 bp. The base composition was AT-biased (82%). Gene order rearrangements were detected and likely to be unique to the genus Monomorium. We announce the M. triviale mitogenome as additional genomic resources for elucidating phylogenetic and taxonomic problems of Monomorium and comparative genomics of parthenogenetic ant species.

摘要

Monomorium是物种最丰富但在分类上有问题的蚂蚁属之一。东亚物种M. triviale Wheeler, WM, 1906，通过专性产雌孤雌生殖进行繁殖，并执行严格的生殖分工。我们使用下一代测序方法对M. triviale丝裂基因组进行了测序。M. triviale的环状有丝分裂基因组长度为 16,290 bp，由 13 个蛋白质编码基因、2 个核糖体 RNA 基因、22 个转移 RNA 和一个 568 bp 的单个非编码区组成。基础成分是 AT 偏向的 (82%)。检测到基因顺序重排并且可能是Monomorium属独有的。我们宣布M. triviale丝裂基因组作为额外的基因组资源，用于阐明Monomorium 的系统发育和分类学问题以及孤雌生殖蚂蚁物种的比较基因组学。
