Data from a study investigating copper-induced oxidative stress on the legume-rhizobia partnership in Lotus japonicus. The dataset, authored by Kathryn Lamoureux and last updated in May 2026, likely contains measurements of plant biomass, copper concentrations, malondialdehyde levels, nitrogen fixation, and ascorbate peroxidase activity under control and copper-treated conditions.
Use Cases
- Modeling the relationship between copper concentration and plant biomass reduction based on described measurements.
- Analyzing the differential accumulation of copper in plant tissues (shoots, roots, nodules) mentioned in the study.
- Investigating indicators of early nodule senescence, such as nitrogen fixation and ascorbate peroxidase activity.
- Studying oxidative stress markers like malondialdehyde in the context of heavy metal contamination.
Strengths
- Dataset is openly licensed under CC-BY-4.0.
- Description provides specific quantitative results (e.g., 30–60% biomass reductions, 300–450 µM copper treatments).
- File is in a widely accessible XLSX format.
Limitations
- Row count is unknown, which may limit suitability assessment.
- Column-level documentation is absent; field semantics must be inferred after download.
- The 36.3 KB file size indicates a very limited data scope.
