Complete mitochondrial genome of Ostrea denselamellosa (Bivalvia, Ostreidae)

Abstract

The complete mitochondrial (mt) genome of the flat oyster, Ostrea denselamellosa, was determined using Long-PCR and genome walking techniques in this study. The total length of the mt genome sequence of O. denselamellosa was 16,227 bp, which is the smallest reported Ostreidae mt genome to date. It contained 12 protein-coding genes (lacking of ATP8), 23 transfer RNA genes, and two ribosomal RNA genes. A bias towards a higher representation of nucleotides A and T (60.7%) was detected in the mt genome of O. denselamellosa. The rrnL was split into two fragments (3′ half, 711 bp; 5′ half, 509 bp), which seems to be the unique characteristics of Ostreidae mt genomes.
