Pangloss: A Tool for Pan-Genome Analysis of Microbial Eukaryotes

Area of Science:

• Genomics
• Computational Biology
• Eukaryotic Systems

Background:

• The pan-genome concept, initially applied to prokaryotes, is increasingly used for eukaryotes.
• Existing software for eukaryotic pan-genome analysis is limited compared to prokaryotic tools.
• Previous work established a computational pipeline using the PanOCT approach for fungal pan-genome analysis.

Purpose of the Study:

• To present Pangloss, a modified and enhanced computational pipeline for eukaryotic pan-genome analysis.
• To provide a tool for gene prediction, pan-genome construction, refinement, and functional characterization.
• To demonstrate Pangloss's utility with case studies in Yarrowia lipolytica and Aspergillus fumigatus.

Main Methods:

• Gene prediction for user-provided genome sets.
• Pan-genome construction and refinement using the synteny-dependent PanOCT approach.
• Functional characterization and visualization of pan-genome data.

Main Results:

• Pangloss successfully constructed and analyzed a species pan-genome for Yarrowia lipolytica.
• The pipeline accurately reconstructed a previously published pan-genome for Aspergillus fumigatus.
• Pangloss integrates gene prediction, pan-genome construction, and functional analysis capabilities.

Conclusions:

• Pangloss offers a robust and versatile solution for eukaryotic pan-genome analysis.
• The tool addresses the need for specialized software in eukaryotic genomics.
• Pangloss is freely available, promoting further research in comparative genomics.
