The complete mitochondrial genome and phylogenetic analysis of Batillaria cumingi (Gastropoda: Batillariidae)

Abstract

We determined the complete mitochondrial genome of Batillaria cumingi. The B. cumingi mitochondrial genome is 16,100 bp in length, comprising 13 protein-coding genes, 22 transfer RNA genes, and two ribosomal RNA genes. The nucleotide composition for B. cumingi is 17.5% of C, 16.88% of G, 35.3% of T, and 30.31% of A. In 13 protein-coding genes, all genes start with ATG. For the stop codon, the cox2 gene stops with TTC, the cytb, nad1, and nad2 genes stop with TAG, and the other nine genes are with TAA. Of these 37 genes identified, nine protein-coding genes and six transfer RNA genes are encoded on the heavy strand and the other genes on the light strand. The phylogenetic tree was constructed based on 13 protein-coding genes of the B. cumingi and other 19 Gastropoda species, Sepia latimanus as outgroup using the Neighbour-joining method. The tree showed that the B. cumingi is closely related to the Semisulcospira coreana in Cerithioidea. We believe that this result will be helpful for the study of population genetic and phylogenetic analysis of the family Batillariidae.
