Summary
We developed a new in silico PCR (sPCR) method to assemble specific genomic regions from raw sequence reads. This tool, sharkmer, aids in validating datasets, identifying contaminants, and building phylogenies.
Area of Science:
- Genomics
- Bioinformatics
- Computational Biology
Background:
- Leveraging existing primer optimization for benchtop PCR.
- Utilizing public archives of gene sequences.
Purpose of the Study:
- Introduce an in silico PCR (sPCR) method for assembling specific genomic regions from raw sequence reads.
- Enable rapid isolation of target genomic regions.
- Facilitate routine bioinformatics tasks.
Main Methods:
- Implement sPCR in sharkmer, a targeted de Bruijn graph assembler.
- Seed the assembler with forward primer sequence and terminate with reverse primer sequence.
- Utilize raw sequence reads for assembly.
Main Results:
- Successfully assemble specific genomic regions using sPCR.
- Demonstrate utility for validating species identity.
- Showcase application in contaminant identification and phylogeny construction.
Conclusions:
- sPCR in sharkmer provides a rapid and efficient method for analyzing genomic data.
- The tool supports critical tasks in species identification, contaminant screening, and phylogenetic analysis.
- Leverages established primer sequences for in silico genomic assembly.
