Description
The dataset documents the phenotypic, physiological, subcellular, and ultrastructural responses of hollyhock (Alcea rosea) plants to cadmium (Cd), lead (Pb), and combined heavy metal stress. It includes measurements of antioxidant enzyme activities, osmoregulatory compounds, cellular chelators, and metal ion distribution and speciation in roots and shoots. The study tested treatments of Cd (30 μmol/L), Pb (200 μmol/L), and their combination.
Use Cases
Analyze the relationship between antioxidant enzyme activities and specific metal treatments (Cd, Pb, Cd+Pb) to model plant stress tolerance.
Compare the subcellular distribution of Cd (primarily in cell walls and soluble fractions) versus Pb (localized to cell walls) across different stress conditions.
Model the impact of combined Cd+Pb stress on key chemical speciation forms (FNaCl, FHAc, FHCl) to assess synergistic toxicity and mobility.
Correlate ultrastructural damage metrics (e.g., heterochromatin reduction, membrane damage) with physiological response data under varying metal stresses.
Strengths
Data is derived from a controlled experimental study with defined treatment concentrations (30 μmol/L Cd, 200 μmol/L Pb).
Analysis covers multiple biological scales: phenotype, physiology, subcellular distribution, chemical speciation, and ultrastructure.
Dataset is openly licensed under CC BY 4.0, permitting reuse and redistribution.
Limitations
The dataset is very small (14.8 KB DOCX file), indicating limited scope and likely a summary table rather than raw experimental data.
Sample size (number of biological replicates or rows) is unknown, limiting statistical power assessment.
Data is presented in a DOCX format, which is not ideal for direct computational analysis and may require manual extraction.
