Current trends in microsatellite genotyping

Area of Science:

• Genetics
• Molecular Biology
• Population Genetics

Background:

• Microsatellites (simple sequence repeats) have been widely used as molecular markers since the late 1980s.
• Despite advancements in genotyping and sequencing, microsatellite marker utility is increasing due to technical improvements.
• Multiplex PCR and next-generation sequencing (NGS) offer cost-effective, high-throughput methods for microsatellite analysis.

Purpose of the Study:

• To evaluate current practices in population genetic studies using microsatellite markers.
• To highlight the gap between available technological advancements and their adoption in research.
• To advocate for standardized protocols and bioinformatic tools for microsatellite analysis.

Main Methods:

• Survey of recently published population genetic studies utilizing simple sequence repeats.
• Analysis of the adoption rates of quality controls and multiplex PCR techniques.
• Review of technical advances in microsatellite genotyping and sequencing.

Main Results:

• Over 50% of recent population genetic studies using microsatellites lack essential quality controls.
• A significant portion of studies do not implement multiplex PCR, a cost- and time-saving technique.
• Despite improvements in NGS and multiplexing, current research practices lag behind technological potential.

Conclusions:

• There is a critical need to update current practices in microsatellite marker application.
• Implementing standardized high-throughput protocols and bioinformatic tools is essential for efficient microsatellite analysis.
• Adopting advanced techniques like multiplex PCR and leveraging NGS data will enhance the quality and efficiency of population genetic studies.
