The complete mitochondrial DNA of the Pacific Geoduck clam ( Panopea generosa ).

The complete mitochondrial genome of the Pacific GeoduckPanopea generosa(Genbank accession KM580067) is 15,585 bp in size and contains the typical 37 genes (13 protein-coding, 2 ribosomal RNA and 22 transfer RNA) found in metazoan mitogenomes, including the rare ATPase subunit 8 gene (ATP8). All genes are coded in the same strand but the gene arrangement is novel among heterodont bivalves. The base composition was: A 25.0%, T 38.7%, C 11.2% and G 25.0%. The genome is structurally similar to that of its congener the Cortes GeoduckPanopea globosa. [ABSTRACT FROM PUBLISHER]
