Abstract
In this study, we sequenced and analyzed the complete mitochondrial genome of Alectryonella plicatula (Gmelin 1791), the newly determined mitochondrial genome is 18225 bp in length, it is a circular molecule and consists of 12 protein-coding genes (atp8 is absent), 24 transfer RNA (with two copies of trnP and trnQ), and 2 ribosomal RNA genes (splitting of the rrnL gene and duplication of the rrnS gene were identified). Phylogenetic analysis based on 12 protein coding genes showed that Alectryonella plicatula is closely related to Crassostrea gigas.
