Lichen Fungal Genomic Data for Symbiosis Evolution Analysis

518.2 MB of supplementary genomic data from a study exploring lichen evolution across the Ascomycota phylum. The dataset includes phylogenomic reconstructions, genome comparisons, and functional annotations like CAZymes, produced by David Diaz Escandon. It supports analyses of genomic signatures distinguishing lichen fungi from non-lichen fungi.

Use Cases

• Perform phylogenomic reconstruction of the Ascomycota tree of life using the provided TRE and CONTREE files to resolve orphan clades like Lichinomycetes.
• Compare fungal genome functional annotations, particularly CAZyme counts, to investigate correlations with photobiont subsidy molecules like erythritol, glucose, sorbitol, or ribitol.
• Apply machine learning on orthogroup data to identify genomic signatures that distinguish lichen fungi from non-lichen fungal genomes.
• Analyze the bimodal pattern in enzymatic machinery repertoires across lichen fungal genomes described in the study.

Strengths

• Dataset size of 518.2 MB indicates substantial genomic and supplementary data.
• Includes multiple file formats (CSV, TRE, YAML, CONTREE, TSV, R, PY, XLSX) for diverse analytical approaches.
• Data is derived from a genomics study covering multiple fungal lineages and symbiotic lifestyles across Ascomycota.
• Clear licensing under CC BY 4.0 for open reuse.

Limitations

• Unknown row and column counts limit precise assessment of dataset scale and structure.
• Data is supplementary to a specific research paper, requiring domain knowledge in mycology and genomics for effective use.
• Sample data is unavailable for preview, making initial inspection of data format and quality difficult.
