Area of Science:

  • Equine genomics
  • Molecular biology
  • Animal genetics

Background:

  • Horse genome analysis is advancing rapidly, with over 1,500 markers mapped in 6-7 years.
  • Approximately half of the mapped markers are genes or expressed sequence tags (ESTs).
  • Equine health, performance, and phenotypic traits are of significant interest to breeders and owners.

Purpose of the Study:

  • To develop critical genomic resources for the equine industry.
  • To identify genes and mutations responsible for inherited equine diseases.
  • To discover genes associated with traits like fertility, disease resistance, coat color, and athletic performance.

Main Methods:

  • Genome-wide marker mapping
  • Gene and EST identification

  • Functional genomic approaches

    • Main Results:

    • Over 1,500 genetic markers, including genes/ESTs, have been mapped in the horse genome.
    • Development of advanced equine gene map resources is underway.
    • Functional genomic strategies are being employed to understand disease manifestation.

    Conclusions:

    • Advancements in equine genomics will facilitate the identification of disease-causing genes and mutations.
    • Genomic resources will aid in developing diagnostics, therapeutics, and prevention strategies for equine disorders.
    • Understanding the equine genome will enhance breeding programs and improve animal welfare through trait discovery.
