Cadmium Stress Dopamine Signaling Dynamics in Duckweed

Fluorescence intensity measurements from a genetically encoded dopamine biosensor in duckweed (Lemna turionifera 5511) under cadmium stress. The dataset includes specific fluorescence values for protoplasts from fronds and roots after a 24-hour exposure to 50 mM CdCl2. Author Bosen Hao published the data on figshare under a CC-BY-4.0 license in June 2026.

Use Cases

• Modeling dopamine signaling dynamics in plants based on fluorescence intensity changes described in the results.
• Investigating the link between heavy metal stress and catecholamine signaling in aquatic plants based on the described experimental setup.
• Benchmarking genetically encoded biosensor performance in plant tissues based on the described GRAB-DA2h application.
• Informing phytoremediation strategy improvements based on the described dopamine response to cadmium.

Strengths

• Dataset provides specific, quantitative fluorescence intensity values (e.g., frond protoplasts increased from 345.18 to 391.14).
• Experimental conditions are clearly defined, including a 50 mM CdCl2 treatment and a 24-hour exposure period.
• Data is published under a permissive CC-BY-4.0 license, facilitating reuse.

Limitations

• Dataset scale is limited to 24.5 KB, suggesting a small number of observations.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
