Gene Duplication Impacts on Legume Root Nodule Symbiosis Evolution

Hyun-oh Lee's dataset, last updated May 12, 2026, analyzes the role of gene duplications in the evolution of root nodule symbiosis in legumes. The 8.1 MB Excel file likely contains data on gene superfamilies and duplication events. It focuses on duplications occurring after the ancient gamma paleohexaploidy event and before the evolution of symbiotic nodules.

Use Cases

• Identify candidate gene families for functional studies based on duplication history.
• Model the timing of gene duplication events relative to the evolution of symbiotic traits.
• Correlate whole-genome duplication events with the gain of novel gene functions in nodulation.

Strengths

• Dataset is 8.1 MB, indicating a detailed but manageable size for analysis.
• Focuses on a specific evolutionary puzzle regarding a ~120 million-year gap between a major duplication event and trait emergence.
• Explicitly examines both ancient whole-genome duplications and more recent local duplications.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The description is highly specialized, which may limit accessibility for non-experts.
