Complete mitochondrial genome of the hard clam (Mercenaria mercenaria).
Ontology highlight
ABSTRACT: The hard clam (Mercenaria mercenaria) is an important economic and ecological bivalve. In this study, the mitochondrial genome was sequenced. The sequenced genome size was 18,360 bp. The nucleotide composition was asymmetric with a AT bias. Mitogenome contained 13 protein-coding genes (PCGs), 2 rRNA genes, and 22 tRNA genes. Of 13 PCGs, 3 genes (cox3, nad3, and cox2) had incomplete stop codons. Furthermore, phylogenetic analysis using 12 PCGs (except atp8) figured out that M. mercenaria was closely related to genus Dosinia. The complete mitogenome of M. mercenaria provides essential information for further phylogenetic and evolutionary analysis in Veneridae.
