Quercetin Effects on Cadmium Tolerance in Amaranth: Physiological and Metabolic Data

A supplementary document details a study on the physiological and metabolic mechanisms of exogenous quercetin in the cadmium hyperaccumulator Amaranthus hypochondriacus L. The research, authored by Yang Zhou and last updated in April 2026, involved applying quercetin at concentrations of 0, 5, 10, and 20 mg·L⁻¹ under varying cadmium levels (0, 4, 20 mg·kg⁻¹). Results include specific measurements such as a 49.5% reduction in electrolyte leakage and a 17.7% increase in chlorophyll content under optimal treatment.

Use Cases

• Modeling the relationship between exogenous quercetin concentration and cadmium tolerance metrics like electrolyte leakage and chlorophyll content.
• Analyzing the activation of the phenylpropanoid flavonoid pathway and its role in heavy metal detoxification.
• Investigating the synergistic mechanism of endogenous flavonoid enhancement coupled with exogenous supplementation for phytoremediation efficiency.
• Studying the role of glutathione (GSH) and related metabolites in cadmium chelation and oxidative stress reduction.

Strengths

• Includes specific quantitative results, such as a 49.5% reduction in electrolyte leakage and a 17.7% increase in chlorophyll content.
• Experimental design is clearly described with defined quercetin (0-20 mg·L⁻¹) and cadmium (0-20 mg·kg⁻¹) treatment levels.
• Released under a permissive CC-BY-4.0 license for open reuse.

Limitations

• Data is provided as a 211.1 KB DOCX file; the underlying structured data (e.g., raw measurements) may require extraction.
• Column-level documentation is absent; field semantics must be inferred from the textual description.
• Row count is unknown, which may limit suitability assessment for quantitative analysis.
