Single-nucleotide polymorphisms in the epsilon-globin gene for differentiating primate infraorders

Area of Science:

• Conservation genetics
• Molecular ecology
• Forensic science

Background:

• Molecular methods are crucial for wildlife conservation law enforcement, aiding in species and origin identification.
• Single-nucleotide polymorphisms (SNPs) offer a promising yet underexplored tool for these applications.
• Primates are a conservation priority, and their geographic distribution varies by infraorder.

Purpose of the Study:

• To develop a reliable and accessible method for identifying primate infraorders using molecular markers.
• To leverage single-nucleotide polymorphisms (SNPs) for enhanced forensic applications in wildlife conservation.
• To facilitate the initial screening of unknown primate samples for taxonomic and geographic origin.

Main Methods:

• Development of a single-base extension technology assay.
• Scoring of 3 informative single-nucleotide polymorphisms (SNPs) within the epsilon-globin gene.
• Application of the method to identify primate infraorders from unknown samples.

Main Results:

• Successfully developed a reliable and easy-to-use method for SNP scoring.
• The method accurately identifies the primate infraorder based on 3 specific SNPs.
• Demonstrated the potential for automated screening of primate samples.

Conclusions:

• The developed SNP-based method offers a valuable tool for primate conservation and law enforcement.
• This technique can aid in the initial automated screening of unknown primate samples at customs.
• Further exploration of SNPs can significantly advance molecular approaches in wildlife forensics.
