Kinetoplastid Phylogenomics Dataset with Proteomes and Phylogenetic Trees

Supplementary data supports a phylogenomic study on free-living neobodonids and metakinetoplastids. The dataset contains two versions, with v1 including 45 species and v2 expanding to 49 species, providing proteomes, contigs, orthogroup sequences, and phylogenetic trees. It was created by Daryna Zavadska and released alongside preprints in October 2025 and April 2026.

Use Cases

• Constructing and comparing phylogenetic trees using the provided TRE, CONTREE, or NEXUS files for 45-49 species.
• Analyzing orthogroup sequence alignments (OG sequences) for phylogenomic marker identification.
• Examining protein-coding gene content across species using the FASTA-formatted proteome files.
• Investigating genomic assembly characteristics via the supplied contig data.
• Reviewing supplementary data tables and analyses contained in the XLSX and PDF files.

Strengths

• Includes two distinct, versioned datasets (v1 with 45 species, v2 with 49 species) allowing for comparative analysis of the expanded phylogeny.
• Provides multiple phylogenetic tree file formats (TRE, CONTREE, NEX) and orthogroup sequence alignments, supporting different analytical workflows.
• Released under a permissive CC-BY-4.0 license, facilitating reuse and redistribution.

Limitations

• The exact row counts and complete column schema are not provided by any source, limiting precise understanding of data structure.
• Sources conflict on total dataset size, reporting 25.7 GB (datacite) and 11.8 GB (figshare), indicating potential differences in hosted content.
