The complete mitochondrial genome of <i>Neptunea arthritica cumingii</i> Crosse, (Gastropoda: Buccinidae)

Abstract

The complete mitochondrial (mt) genome of the Neptune whelk, <i>Neptunea arthritica cumingii</i>, was determined using genome walking techniques in this study. The total length of the mt genome sequence of <i>N. arthritica cumingii</i> was 15 256 bp, including 13 protein-coding genes, 21 transfer RNA genes and 2 ribosomal RNA genes. The overall composition of the mitogenome was estimated to be 30.85% for A, 38.59% for T, 15.15% for C and 15.40% for G, indicating that an A + T (69.44%)-rich feature occurs in the <i>N. arthritica cumingii</i> mitogenome. The phylogenetic relationships of 11 mollusc species were constructed based on the complete mtDNA sequences by the neighbour-joining method using MEGA 5.0 software (MEGA Inc., Englewood, NJ).
