ABSTRACT

Mitochondrial genomes have proved to be a powerful tool in resolving phylogenetic relationship. In order to understand the mitogenome characteristics and phylogenetic position of the genus Dosinia, we sequenced the complete mitochondrial genomes of Dosinia altior and Dosinia troscheli (Bivalvia: Veneridae), compared them with that of Dosinia japonica and established a phylogenetic tree for Veneridae. The mitogenomes of D. altior (17,536 bp) and D. troscheli (17,229 bp) are the two smallest in Veneridae, which include 13 protein-coding genes, 2 ribosomal RNA genes, 22 tRNA genes, and non-coding regions. The mitogenomes of the Dosinia species are similar in size, gene content, AT content, AT- and GC- skews, and gene arrangement. The phylogenetic relationships of family Veneridae were established based on 12 concatenated protein-coding genes using maximum likelihood and Bayesian analyses, which supported that Dosininae and Meretricinae have a closer relationship, with Tapetinae being the sister taxon. The information obtained in this study will contribute to further understanding of the molecular features of bivalve mitogenomes and the evolutionary history of the genus Dosinia.
