Comparative mitogenomic analyses of three scallops (Bivalvia: Pectinidae) reveal high level variation of genomic organization and a diversity of transfer RNA gene sets.

ABSTRACT:

Background

It can be seen from the available mollusk mitogenomes that the family Pectinidae exhibits the most variation in genome organization. In this study, comparative mitogenomic analyses were performed for three scallops from the subfamily Chlamydinae (Pectinidae), with the goal of characterizing the degree of variability of mitogenome organization and other characteristics among species from the same subfamily and exploring their possible evolution route.

Findings

The complete or nearly complete mtDNA sequences of scallop Mimachlamys nobilis (17,935 bp), Mizuhopecten yessoensis (20,964 bp) and Chlamys farreri (17,035 bp) were determined using long PCR amplification and primer walking sequencing strategy. Highly variable size difference of the three genomes resulted pri
