Summary
Genetic analysis reveals distinct populations of rhesus and long-tailed macaques in Southeast Asia. A new quantitative real-time PCR (qPCR) assay accurately identifies macaque species and detects hybrids, with 3 of 19 Vietnamese long-tailed macaques identified as hybrids.
Area of Science:
- Primatology
- Genetics
- Molecular Biology
Background:
- Regional macaque populations (rhesus and long-tailed) show genetic divergence between mainland and insular Southeast Asia.
- Previous research indicates genetic admixture between these macaque species due to natural and human-assisted hybridization.
Purpose of the Study:
- To develop a quantitative real-time PCR (qPCR) assay for efficient species identification of macaque biological samples.
- To quantify species-specific DNA templates for accurate genetic analysis.
- To assess the prevalence of hybridization in regional macaque populations.
Main Methods:
- Development and application of a quantitative real-time PCR (qPCR) assay.
- Amplification of DNA from 109 regionally representative rhesus and long-tailed macaques.
- Determination of species of origin and quantification of template DNA.
Main Results:
- The qPCR assay successfully determined species identity and quantified DNA concentrations.
- Analysis of 19 Vietnamese long-tailed macaques revealed 3 hybrid samples.
- Demonstrated the utility of qPCR for identifying genetic admixture in macaque populations.
Conclusions:
- The developed qPCR assay is an efficient tool for macaque species identification and DNA quantification.
- Hybridization occurs in regional macaque populations, as evidenced by the detection of hybrids.
- Accurate species identification and DNA quantification are critical for cost-effective and reliable genetic studies of macaques.
