Corbicula Japonica High-Quality Genome Assembly with 21,235 Annotated Genes

A 1.04 Gb genome assembly for the brackishwater clam Corbicula japonica, spanning 19 pseudochromosomes with a scaffold N50 of 58.95 Mb. Hyeongwoo Choi published this resource on figshare in May 2026, providing 21,235 predicted protein-coding genes with 95.3% functional annotation. Genome completeness assessment using BUSCO with the mollusca_odb12 dataset demonstrated 94.7% completeness.

Use Cases

• Study molecular mechanisms of environmental adaptation based on the annotated genome of a species adapted to fluctuating salinity.
• Conduct comparative genomics analyses based on the high-quality, chromosome-scale assembly.
• Support selective breeding programs in aquaculture based on the identified protein-coding genes.
• Investigate population genetics and evolutionary history based on the genomic resource for Corbicula japonica.

Strengths

• High-quality assembly metrics: 1.04 Gb genome with a scaffold N50 of 58.95 Mb.
• High completeness: 94.7% BUSCO completeness score using the mollusca_odb12 dataset.
• Comprehensive annotation: 21,235 predicted protein-coding genes with 95.3% functional annotation.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for some analyses.
