179,942 nonredundant structural variants were identified from 18 European commercial and Southern Chinese local pigs using PacBio HiFi long-reads. The dataset, authored by Di Tang and released under CC-BY-4.0, reveals 943 SV hotspot regions and introgression from Chinese breeds into Duroc pigs. Integration with transcriptomic data from adipose tissue demonstrates these variants regulate key metabolic genes.
Use Cases
- Identify adaptive introgressed haplotypes based on the 907 putative introgressed regions per donor breed
- Study the regulatory role of structural variants on gene expression using the integrated transcriptomic data from adipose tissue
- Analyze population genetic differentiation between Chinese indigenous and European pigs using the catalog of 179,942 SVs
- Investigate candidate regions for phenotypic evolution based on the two strong haplotype sharing regions on chromosomes 2 and 14
Strengths
- High-resolution SV catalog comprising 179,942 nonredundant structural variants
- Analysis integrates data from 370 global samples, including ancient genomic data
- Identifies 943 SV hotspot regions and specific introgressed candidate regions
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
- Data may reflect geographic bias inherent to the 18 European and Southern Chinese pig samples
