Symbiosis island (SI) acquisition is sufficient to generate de novo root nodule-forming endosymbionts, with one-third arising immediately as nitrogen-fixing mutualists. This dataset contains experimental data and R code for a study investigating the genetics and fitness effects of incipient endosymbiosis in Mesorhizobium bacteria. It was authored by Angeliqua Montoya and last updated on April 24, 2026.
Use Cases
- Modeling the fitness effects of symbiosis island transfer based on greenhouse experiment data
- Analyzing the genetics of early niche expansion into endosymbiosis based on genomic data
- Studying the frequency of SI gain transconjugants based on mating experiment results
- Investigating the transition from commensalism to mutualism in novel endosymbionts based on plant and rhizobium fitness measurements
Strengths
- Includes data from two distinct experiments: SI transfer and greenhouse fitness assessments
- Associated R code for analyses is provided
- Last updated on April 24, 2026
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
