Ridged-Eye Flounder Telomere-to-Telomere Genome Assembly, 489 Mb

A 489.00 Mb gap-less telomere-to-telomere genome assembly for the ridged-eye flounder (Pleuronichthys cornutus) integrates DNBSEQ, PacBio HiFi, Hi-C, and ONT ultra-long sequencing. The assembly has a contig N50 of 20.11 Mb, with 94.21% of sequences anchored onto 24 chromosomes and 22,560 identified protein-coding genes. Weiwei Zheng published this resource on figshare in May 2026.

Use Cases

• Studying chromosome structure and telomere biology based on the telomere-to-telomere assembly and identified telomeres.
• Comparative genomics analysis of flatfish species based on the 22,560 annotated protein-coding genes.
• Investigating repetitive element composition and evolution based on the 19.69% (96.28 Mb) of the genome classified as repetitive.
• Benchmarking genome assembly pipelines based on the integration of multiple sequencing technologies described.

Strengths

• Gap-less telomere-to-telomere assembly, a high-quality standard in genomics.
• High contiguity with a contig N50 length of 20.11 Mb.
• High chromosome anchoring rate of 94.21% onto 24 chromosomes.
• Comprehensive functional annotation covering 96.28% of the 22,560 identified protein-coding genes.

Limitations

• Row count and column-level documentation are absent, requiring manual inspection after download.
• The dataset's 97.0 MB size suggests it contains processed annotations rather than raw sequencing reads, limiting certain analyses.
• Data may reflect biases inherent to the specific specimen sequenced and the figshare platform's scope.
