Abstract
In this study, the complete mitochondrial genome (mitogenome) of Helice sheni was amplified and analyzed. The mitogenome is 16,062 bp in length, encoding the standard set of 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, and one control region. The nucleotide frequency of the mitogenome is as follows: A, 34.81%; C, 23.24%; G, 12.68%; and T, 29.25%. Eight overlapping areas and 22 intergenic spacers were found in the complete mitogenome. The typical initiation codon (ATT) and stop codon (TAA) were observed in eight genes, respectively. The phylogenetic tree indicates that Helicana wuana is closely related to H. sheni.
