Abstract
The complete mitochondrial genome of Zhikong scallop Chlamys farreri is 21,695 bp in length and contains 12 protein-coding genes (the atp8 gene is absent, as in most bivalves), 2 ribosomal RNA genes, and 22 transfer RNA genes. The heavy strand has an overall A+T content of 58.7%. GC and AT skews for the mt genome of C. farreri are 0.337 and −0.184, respectively, indicating the nucleotide bias against C and A. The mitochondrial gene order of C. farreri differs drastically from the scallops Argopecten irradians, Mimachlamys nobilis and Placopecten magellanicus, which belong to the same family Pectinidae. 6623 bp non-coding nucleotides exist intergenically in the mitogenome of C. farreri, with a large continuous sequence (4763 bp) between tRNA Val and tRNA Asn. Two repeat families are found in the large continuous sequence, which seems to be a common feature of scallops. Phylogenetic analysis based on 12 concatenated amino acid sequences of protein-coding genes supports the monophyly of Pectinidae and paraphyletic Pteriomorphia with respect to Heteroconchia.
