Pig Genomic Information System (PigGIS) is a web-based resource for pig (Sus scrofa) genomic data. This system aids biomedical research by locating pig genes and single nucleotide polymorphisms (SNPs).

Area of Science:

  • Genomics
  • Bioinformatics
  • Comparative Genomics

Background:

  • The pig genome (Sus scrofa) presents unique challenges for genomic analysis due to its complexity.
  • Biomedical research requires robust tools for identifying pig genes and genetic variations like single nucleotide polymorphisms (SNPs).

Purpose of the Study:

  • To develop and present the Pig Genomic Information System (PigGIS), a web-based platform for pig genomic data.
  • To facilitate the location of pig genes homologous to human genes and map SNPs across diverse pig populations.

Main Methods:

  • Integration of various sequence data, including whole genome shotgun (WGS) reads and expressed sequence tags (ESTs).
  • Development of mapping solutions to address challenges associated with low-coverage genomes.
  • Utilizing bioinformatics approaches for data analysis and resource development.

Main Results:

  • Identification of 15,700 pig consensus sequences, covering 18.5 Mb of homologous human exons.
  • Recovery of 18,700 single nucleotide polymorphisms (SNPs) for genetic studies.
  • Generation of 20,800 unique 60mer oligonucleotide probes for future pig genome analyses.

Conclusions:

  • PigGIS provides a valuable, web-accessible resource for pig genomic research.
  • The system successfully addresses low-coverage genome mapping and aids in identifying key genomic features for biomedical applications.
