The complete mitochondrial genome of Chinese land snail Aegista aubryana (Gastropoda: Pulmonata: Bradybaenidae)

Abstract

Aegista aubryana is an endemic land snail in China. The complete mitochondrial genome of A. aubryana was first determined using long PCR reactions and primer walking method (accession number KT192071). The genome has a length of 14 238 bp, containing 37 typical mitochondrial genes (13 protein-coding genes, 22 tRNA genes and 2 rRNA genes). The base composition of the whole heavy strand is A 31.32%, T 37.86%, C 14.46% and G 16.36%. The results of phylogenetic analyses showed that the A. aubryana is most closely related to Mastigeulota kiangsinensis. This new complete mitochondrial genome can be the basic data for further studies on mitogenome comparison, molecular taxonomy and phylogenetic analyses in bradybaenid snails and Molluscs at large.

Complete mitochondrial genome of the land snail Euphaedusa planostriata (Gastropoda: Stylommatophora: Clausiliidae)

“…Similar to other stylommatophoran mitogenomes, it contains 13 PCGs, 22 tRNA genes, 2 rRNA genes, and a non-coding control region with 1,555 bp. The entire mitogenome of E. planostriata had a high A þ T content of 70.10%, in accordance with other land mollusks (Deng et al 2016;Yang et al 2016;Xie et al 2019). The overall nucleotide composition is as follows: A ¼ 31.7%, C ¼ 13.9%, G ¼ 16.0%, and T ¼ 38.4%.…”
