Genome assembly and annotation files of sea scallop Placopecten magellanicus

Placopecten magellanicus (Gmelin), a deep-sea Atlantic scallop naturally found along the northwest Atlantic coast, is a commercially essential benthic large marine bivalve. Given the commercial importance of sea scallop P. magellanicus, it is necessary to reconstruct its genome to benefit the further exploration of natural resources, even genetic breeding. Herein, we first reported a high-quality chromosome-level genome of sea scallop P. magellanicus using a combination of Illumina short read sequencing, PacBio HiFi reads, and Hi-C sequencing. Our approach allowed us to obtain a final assembly comprising 1,778 Mb of sequence and a N50 scaffold of 86.71 Mb.
