Gene Duplication Impacts on Root Nodule Symbiosis in Legumes

A study focusing on gene superfamilies with whole genome duplications occurring after the gamma triplication (~120 million years ago) and prior to the evolution of root nodule symbiosis. The research identifies several gene families that are essential for symbiosis and shows evidence of critical roles for both ancient and recent duplications. The dataset is a PDF document authored by Hyun-oh Lee, last updated on 2026-05-12.

Use Cases

• Study the evolutionary history of gene families involved in root nodule symbiosis based on the analysis of whole genome duplications.
• Identify candidate genes for neo- or sub-functionalization events related to symbiosis based on duplication timing analysis.
• Model trait gain and loss of nitrogen-fixing nodulation across approximately 13,000 rosid species based on phylogenetic inference mentioned in the description.

Strengths

• Focuses on a specific evolutionary puzzle regarding the timing of whole genome duplications and the origin of symbiosis.
• Analysis is based on a broad phylogenetic context within the nitrogen-fixing nodulation clade.

Limitations

• The primary data format is a PDF (82.9 KB), which likely contains textual and graphical analysis rather than raw, structured data tables.
• Row and column counts for any underlying data are unknown, limiting suitability assessment for computational analysis.
• Description metadata is limited; actual data quality requires manual inspection after download.
