Comparative genomic data of the Avian Phylogenomics Project

Area of Science:

• Genomics
• Evolutionary Biology
• Bioinformatics

Background:

• The evolutionary history of modern birds is a long-standing challenge in systematic biology.
• Understanding avian evolutionary relationships requires comprehensive genomic data.

Purpose of the Study:

• To construct a genome-scale avian phylogenetic tree.
• To perform comparative genomics analyses across diverse avian species.
• To release valuable genomic datasets for future research.

Main Methods:

• Sequenced 38 new avian genomes using Illumina HiSeq 2000.
• Assembled genomes via whole genome shotgun strategy.
• Categorized assemblies into high-depth and low-depth groups based on coverage and N50 scaffold size.

Main Results:

• Generated genome assemblies for 48 avian species in total.
• High-depth assemblies (>50X) achieved N50 scaffold sizes >1 Mb.
• Low-depth assemblies (~30X) yielded average N50 scaffold sizes of ~50 kb.
• Annotated 13,000–17,000 protein-coding genes per genome.

Conclusions:

• Released full genome assemblies for 38 avian species.
• Provided access to genomic data from the Avian Phylogenomics Project.
• This project represents the largest vertebrate comparative genomics effort to date.
• The released data will accelerate research in phylogenetics, evolution, and developmental biology.
