摘要
In this study, we determined the complete mitochondrial genome of Loligo beka. The genome was 17 483 bp in length and contained 13 protein-coding genes, 22 transfer RNA genes, two ribosomal RNA genes, and three main non-coding regions. The overall base composition of L. beka is A 40.35%, T 32.53%, C 18.53%, and G 8.58%, with a highly A + T bias of 72.89%. All the three control regions (CR) contain termination-associated sequences and conserved sequence blocks. Here we describe a phylogenetic analysis of 11 species cephalopoda based on the complete mitochondrial genome, the result showed that the Loliolus uyii is most closely related to L. beka. This mitogenome sequence data would play an important role in the investigation of phylogenetic relationship, taxonomic resolution and phylogeography of the cephalopoda.
