Panarthropod NK-Cluster Gene Orthologs and Duplications

Supplementary Material 11 provides a schematic representation of NK-cluster gene orthologs and paralogs across 17 panarthropod species, including Drosophila melanogaster and Tribolium castaneum. The data, created by Ralf Janssen, is an Excel file (10.6 KB) last updated on 2026-04-17. It visualizes gene presence, absence, and duplications, with a focus on species within the Arachnopulmonata group.

Use Cases

• Comparative analysis of NK-cluster gene conservation based on ortholog presence/absence patterns.
• Studying the impact of whole genome duplication events on gene copy number in Arachnopulmonata species.
• Phylogenetic mapping of NK1 and NK2 cluster gene distributions across diverse panarthropod lineages.

Strengths

• Includes data for 17 distinct species, enabling broad comparative analysis.
• Highlights putative gene absences and duplications, particularly for Arachnopulmonata.
• Released under the permissive CC-BY-4.0 license for open reuse.

Limitations

• The dataset is very small (10.6 KB), indicating limited scope and likely a summary visualization.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for quantitative analysis.
