Chromosome-level genome assembly of the estuarine Corbicula flumnalis from the Yangtze River estuary in China

Corbicula clams are of important economic values. Corbicula clams have diverse reproductive characteristics, inhabiting both freshwater and estuary. Here, we constructed a chromosome-level genome of the estuarine C. fluminalis from China by combining HiFi sequencing and Hi-C technology. The assembled genome is 1,140.30 Mb with a scaffold N50 length of 58.80 Mb, and is anchored onto 19 pseudo-chromosomes. A total of 25,363 protein-coding genes were identified and 94.03% of the identified genes were annotated. Approximately 63.50% of the genome is consisted of repetitive elements. The genome synteny between C. fluminalis and Mercenaria mercenaria is highly conserved. The chromosome genome assembly of C. fluminalis is a valuable resource for active ingredient research, phylogenomic studies and comparative genomics of the Corbicula clams and related species.
