Two T2T and One Near-T2T Genome Assemblies for Osteoglossid Fish Species

Chao Bian published two telomere-to-telomere (T2T) chromosome-level genome assemblies for pirarucu and Australian bonytongue and a near-T2T assembly for black arowana on figshare in 2026. The dataset comprises genome sequence files totaling 682.1 MB. BUSCO completeness scores for all assemblies exceed 97%, surpassing most prior assemblies for this fish family.

Use Cases

• Comparative genomic analysis based on high-quality assemblies for three Osteoglossidae species.
• Phylogenetic studies of ancient freshwater fish lineages based on chromosome-level genome data.
• Investigating historical biogeography and transcontinental disjunction patterns based on genomic features.
• Benchmarking genome assembly and annotation methods based on high-BUSCO-completeness reference sequences.

Strengths

• Two T2T chromosome-level genome assemblies and one near-T2T assembly.
• BUSCO completeness scores greater than 97% for all assemblies.
• Assemblies are described as markedly surpassing most previous osteoglossid assemblies.

Limitations

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