Tobacco Cold Stress Response Data: Physiological and Transcriptomic Measurements

A 36.9 KB Excel dataset from a 2026 study on tobacco plant responses to cold stress. The data, published by Hang Li on figshare under CC-BY-4.0, likely contains measurements from NtGCN2-overexpressing and wild-type plants exposed to 4°C for 12 hours. It includes results for antioxidant activity, ABA and chlorophyll content, and transcriptomic profiling.

Use Cases

• Analyzing the relationship between NtGCN2 overexpression and chlorophyll retention based on measured chlorophyll content.
• Investigating proline accumulation as an osmotic adjustment mechanism under cold stress.
• Studying antioxidant defense systems based on superoxide dismutase and catalase activity data.
• Examining ABA regulation pathways based on the upregulation of biosynthetic genes like NCED1.
• Correlating transcriptomic changes with physiological outcomes like reduced MDA levels.

Strengths

• Data is associated with a detailed, peer-reviewed-style methodology described in the source publication.
• The dataset is small (36.9 KB), facilitating quick download and initial inspection.
• Released under a permissive CC-BY-4.0 license, allowing for broad reuse.

Limitations

• Row count is unknown, which may limit suitability assessment for large-scale analysis.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is tiny in scale (36.9 KB), indicating a very limited experimental scope.
