PGCGAP

PGCGAP performs prokaryotic genomic and comparative genomic analyses, including genome assembly, gene prediction, functional and COG annotation, pan-genome and orthologous gene group inference, genomic distance estimation, phylogenetic analysis, variant calling, and screening for antimicrobial resistance and virulence genes.

Key Features:

• Genome Assembly and Annotation: Assembles microbial genomes and predicts genes followed by functional annotation.
• Comparative Genomics Tools: Estimates genomic distances between prokaryotic species or strains for comparative analyses.
• Phylogenetic Analysis: Performs phylogenetic analyses to infer evolutionary relationships among microbial genomes.
• COG Annotation and Pan-genome Analysis: Performs COG (Clusters of Orthologous Groups) annotation and pan-genome analysis across strains or species.
• Orthologous Gene Group Inference: Infers orthologous gene groups to identify conserved genes and evolutionary dynamics.
• Variant Calling and Annotation: Detects genetic variants and annotates them to assess potential functional impact.
• Antimicrobial and Virulence Gene Screening: Screens genomes for antimicrobial resistance genes and virulence factors.

Scientific Applications:

• Microbial Taxonomy: Delineates species and strains using genomic distances and phylogenetic information.
• Comparative Genomics: Compares gene content and genome structure across strains or species via pan-genome and ortholog analyses.
• Evolutionary Studies: Investigates evolutionary relationships and gene conservation using phylogenetics and ortholog inference.
• Antimicrobial Resistance Research: Identifies and monitors antimicrobial resistance genes within microbial genomes.
• Virulence and Pathogenicity Research: Detects virulence factors to study pathogenicity determinants and their distribution.

Methodology:

Performs genome assembly, gene prediction, functional and COG annotation, estimation of genomic distances, pan-genome analysis, orthologous group inference, phylogenetic analysis, variant calling and annotation, and screening for antimicrobial resistance and virulence genes.
