Chromosome-Level Genome Annotation for Female Acrossocheilus Parallens

Genome annotation files detail the functional elements of a 932.63 Mb chromosome-level assembly for the female Acrossocheilus parallens fish. The assembly was generated using PacBio HiFi reads at 152× coverage and scaffolded with Hi-C technology, anchored onto 25 chromosomes with a 98.19% anchor rate. The dataset was authored by 珊 姜 and last updated in March 2026.

Use Cases

• Identify gene structures and coding sequences (CDS) within the GFF3 annotation files for functional analysis.
• Extract protein sequences (PEP files) for proteomic studies and phylogenetic comparisons.
• Analyze the 25 anchored chromosomes to study synteny and genome organization in Barbinae species.
• Use the genome assembly statistics (932.63 Mb size, 98.19% anchor rate) for benchmarking assembly and scaffolding methods.

Strengths

• Chromosome-level assembly with a high 98.19% anchor rate onto 25 chromosomes.
• High-quality PacBio HiFi sequencing at 152× coverage provides a solid foundation for annotation.
• Includes multiple standard annotation file formats (GFF3, CDS, PEP) for different analyses.

Limitations

• Dataset is specific to a single female specimen, limiting population-level genetic insights.
• Annotation quality is dependent on the underlying assembly and may contain errors common to automated pipelines.
