Duckweed Dopamine Signaling Dynamics Under Cadmium Stress

Fluorescence intensity data from transgenic duckweed lines expressing the GRAB-DA2h biosensor, showing dopamine signaling changes under cadmium stress. The dataset includes protoplast measurements, such as an increase from 345.18 to 391.14 in fronds after 24-hour exposure to 50 mM CdCl2. Bosen Hao authored this dataset, which was last updated on 2026-06-01.

Use Cases

• Modeling early plant stress responses based on rapid dopamine signaling dynamics.
• Investigating heavy metal phytoremediation efficiency based on neurotransmitter-like signaling pathways.
• Developing biosensor-based monitoring techniques for plant physiology based on the GRAB-DA2h sensor application.

Strengths

• Includes specific fluorescence intensity measurements (e.g., 345.18 to 391.14) from controlled experiments.
• Uses a genetically encoded fluorescent dopamine sensor (GRAB-DA2h) for real-time visualization.
• Focuses on a specific plant model (Lemna turionifera 5511) under defined cadmium stress conditions.

Limitations

• Dataset size is 399.8 KB, indicating a very limited scope of data.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
