Blowfly genomics: current insights, knowledge gaps, and future perspectives

Area of Science:

• Entomology
• Genomics
• Bioinformatics

Background:

• Blowflies (Calliphoridae) are a diverse insect family with significant ecological and economic roles.
• Despite advances in genomics, publicly available genome assemblies for blowflies are limited, primarily focusing on medically/veterinary important species.
• Existing genetic databases (DNA barcodes, mitogenomes, genomes) cover a small fraction of the known blowfly diversity.

Purpose of the Study:

• To provide a quantitative overview of the available genetic information for blowflies.
• To identify and highlight substantial gaps in public genomic databases for the Calliphoridae family.
• To emphasize the need for increased genome sequencing across diverse blowfly subfamilies and genera.

Main Methods:

• Review and quantitative analysis of publicly available genetic data for blowflies (Calliphoridae) from sources like NCBI.
• Assessment of the representation of known blowfly diversity within DNA barcode, mitogenome, and genome databases.
• Identification of underrepresented subfamilies and genera in genomic research.

Main Results:

• DNA barcodes, mitogenomes, and genome assemblies represent only 16.5%, ~3%, and <1% of known blowfly species diversity, respectively.
• While 183 genomics-related BioProjects exist, many blowfly subfamilies and genera lack genomic representation.
• Significant disparities exist in genomic data availability across different blowfly lineages.

Conclusions:

• There is an urgent need for high-quality reference genomes for a broader range of blowfly species.
• Expanding genomic sequencing efforts is crucial for advancing blowfly identification, systematics, phylogenetics, and evolutionary studies.
• Targeting underrepresented species across all blowfly subfamilies will facilitate a new era of rapid, low-cost genomic research.
