Modeled Carbon-Nitrogen Supply Ratios for Legume-Rhizobium Symbiosis

A 9.5 KB Excel file presents a comparative advantage model of carbon–nitrogen exchange in legume–Rhizobium symbiosis. The model, authored by Toshiko Furukawa and last updated in May 2026, incorporates ATP budget constraints and energy–mass balance to predict supply ratios. It aligns key predictions, such as conditions for symbiosis establishment and exchange patterns, with empirical results.

Use Cases

• Testing model predictions about symbiosis establishment based on ATP cost constraints.
• Analyzing the relationship between host C:N ratio and carbon supply proportion.
• Investigating trade-off patterns in nutrient exchange between symbiotic partners.
• Validating theoretical ecological models against reported empirical exchange patterns.

Strengths

• Model is explicitly aligned with three key empirical results mentioned in the description.
• Data is openly licensed under CC-BY-4.0.
• File size is small (9.5 KB), facilitating quick inspection and download.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset's small scale suggests it contains model outputs or parameters, not extensive observational data.
