Abstract

The complete mitochondrial genome of Nerita yoldii has been determined. The whole sequence was 15,719 bp in length and included 13 protein-coding genes, 22 transfer RNA genes, and two ribosomal RNA genes (12S rRNA and 16S rRNA). The overall base composition is A 29.5%, C 13.8%, G 21.5%, and T 35.2%. In 13 protein-coding genes, the nad2, nad5, and nad6 gene start with ATT, whereas nad4 started with ATA, the other nine genes start with ATG. For the stop codon, COX1, COX3, nad3, and atp8 end with TAG, other nine genes end with TAA. Phylogenetic tree was constructed based on 13 protein-coding genes sequences of Archaeogastropoda species, and the result showed that N. yoldii is most closely related to Clithon retropictus. These mitogenome sequence data will be useful for population genetics and phylogenetic analysis of the family Neritidae.
