The Farm Animal Genotype-Tissue Expression (FarmGTEx) Project

Area of Science:

• Animal Genetics
• Genomics
• Transcriptomics

Background:

• Farm animals exhibit diverse genotypes and phenotypes due to evolutionary forces like mutation, drift, selection, and migration.
• Understanding the genetic basis of these variations is crucial for animal breeding and welfare.

Purpose of the Study:

• To introduce the Farm Animal Genotype-Tissue Expression (FarmGTEx) Project.
• To elucidate the genetic determinants of gene expression across 16 domestic species.
• To investigate context-specific regulatory effects on complex phenotypes.

Main Methods:

• Collecting multiomics data, including genomics and transcriptomics.
• Analyzing data from 50 tissues of 1,000 healthy adult animals per species.
• Including an additional 200 animals per species representing specific contexts.

Main Results:

• The project will generate a comprehensive dataset linking genotypes to gene expression patterns.
• It will identify genetic variations influencing gene regulation in various tissues and conditions.
• The FarmGTEx project will establish a foundation for understanding molecular mechanisms of phenotypic diversity.

Conclusions:

• FarmGTEx will provide crucial insights into the genetic architecture of farmed animal traits.
• The project will advance sustainable agriculture, comparative biology, and potentially human biomedicine.
• Coordinated data analysis and resource sharing are essential for maximizing the project's impact.
