Gene Duplication Impacts on Legume Root Nodule Symbiosis Evolution

78.1 KB PDF document analyzes the role of gene duplication in the evolution of root nodule symbiosis (RNS) in legumes. The study focuses on gene superfamilies with additional independent whole genome duplications occurring after the gamma paleohexaploidy (~120 Mya) and prior to RNS evolution. Author Hyun-oh Lee published the document under CC-BY-4.0 license on figshare in May 2026.

Use Cases

• Modeling trait gain and loss of root nodule symbiosis across approximately 13,000 rosid species based on phylogenetic analysis.
• Identifying gene superfamilies essential for RNS that show evidence of critical roles from ancient and recent duplications.
• Investigating the evolutionary puzzle of RNS emergence tens of millions of years after the last common whole genome duplication event.

Strengths

• Focuses on a specific evolutionary puzzle regarding RNS timing relative to the gamma paleohexaploidy (~120 Mya).
• Analyzes a collection of gene superfamilies with independent whole genome duplications in the interim period.
• Published under an open CC-BY-4.0 license facilitating reuse.

Limitations

• Dataset is a 78.1 KB PDF document; actual structured data tables are not provided.
• Column-level documentation is absent; field semantics must be inferred from the text.
• Row count is unknown, which may limit suitability assessment for computational analysis.
