PypeAmplicon

PypeAmplicon processes amplicon sequencing data to isolate short genomic regions containing single nucleotide polymorphisms (SNPs) and generate individual genotypes for population genetic analyses.

Key Features:

• Reduced SNP Set Isolation: Provides a systematic approach for isolating short genomic regions containing single nucleotide polymorphisms (SNPs) for targeted amplicon sequencing, enabling focus on informative markers without whole-genome sequencing.
• Automated Data Processing: Automates the processing of raw sequence reads into individual genotypes for datasets generated by high-multiplexed PCR and next-generation sequencing.
• Empirical Recovery Rates (Belgica antarctica): Demonstrated recovery of 81% of designed amplicons and successful genotyping of 76% of targeted SNPs in the Antarctic midge Belgica antarctica.
• Discovery of Novel SNPs: Sequencing approximately 150 base pairs around targeted regions identified 80 additional novel SNPs.
• Comparative Analysis Capability: Enables comparison of amplicon data with low-coverage whole-genome resequencing (lcWGR) data to produce results comparable to lcWGR for population genetic inference.

Scientific Applications:

• Population genetics data development: Supports efficient development of population genetic datasets from targeted amplicon sequencing.
• Non-model organism studies: Applicable to marker development and genotyping in non-model organisms such as Belgica antarctica.
• Conservation genetics: Facilitates targeted marker generation and genotyping for conservation and management studies.
• Evolutionary biology and ecological genomics: Provides targeted SNP data for studies of evolutionary processes and ecological genomic patterns.

Methodology:

Integrates high-multiplexed PCR with next-generation sequencing to generate amplicon data and processes raw sequence reads through automated steps to extract individual genotypes, with support for comparison to low-coverage whole-genome resequencing (lcWGR) datasets.
