Abstract

Arion ater are a group of mollusks, almost all of which live in a dark and humid environment during their life cycle. In this study, the complete mitogenome of Arion ater was sequenced using next generation sequencing, analyzed and compared with other Stylommatophorans. The total length of the mitochondrial genome is 14,314 bp and consists of 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, and 1 control region. The genome has a typical mitochondrial gene sequence of Arion. Phylogenetic analysis of the mitochondrial genomes of 27 species of Stylommatophora showed that the Arion ater, Arion rufus and Arion vulgaris forms a monophyletic group with other species.

Highlights

  • Arion ater are a group of mollusks, almost all of which live in a dark and humid environment during their life cycle

  • The eggs of Arion ater are produced in the soil crevices with high humidity and concealment

  • The complete mitochondrial genome Arion ater was sequenced and analyzed, which is helpful to identify the species and locate the evolutionary relationship of Arion ater, so that it can be used from a biological perspective

Summary

Introduction

Arion ater are a group of mollusks, almost all of which live in a dark and humid environment during their life cycle. KEYWORDS Arion ater; mitochondrial genome; phylogenetic tree Arion ater (Stylommatophora: Arionidae), known as a slug, is hermaphrodite, and can reproduce by interfertilization (Wright 1974). The eggs of Arion ater are produced in the soil crevices with high humidity and concealment.
