Sarcophaga Peregrina Chromosome-Level Genome Assembly

560.31 Mb chromosome-scale genome assembly for the flesh fly Sarcophaga peregrina, with a contig N50 of 3.84 Mb. Lipin Ren from Central South University led the work, which identified 14,476 protein-coding genes and 45.70% repeat elements. The assembly anchors six pseudochromosomes and provides insights into the species' ovoviviparous reproduction and necrophagous habits.

Use Cases

• Conducting phylogenetic analysis based on the provided genome to estimate divergence times, such as the ~7.14 Mya split from S. bullata.
• Studying gene family expansion and positive selection related to traits like horionic membrane formation and Dorso-ventral axis formation.
• Investigating genetic bases for lipid metabolism and olfactory receptor activity linked to necrophagous feeding habits.
• Using the annotated genome as a reference for comparative genomics with other dipteran species.

Strengths

• Chromosome-level assembly with six pseudochromosomes reliably anchored via Hi-C scaffolding, covering 97.76% of the genome.
• High-quality annotation with 14,476 protein-coding genes functionally annotated, accounting for 92.14% of predicted genes.
• Detailed characterization of genomic features, including a 560.31 Mb size, 3.84 Mb contig N50, and identification of 45.70% repeat elements.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for specific analyses.
• Last update date is unknown; freshness unverified.
