NtGCN2 Role in Tobacco Cold Tolerance: Physiological and Transcriptomic Data

Research data from a study on the NtGCN2 gene's role in cold tolerance in tobacco plants (Nicotiana tabacum L.). The dataset, authored by Hang Li and last updated in May 2026, likely contains physiological measurements and transcriptomic profiles from NtGCN2-overexpressing and wild-type plants subjected to 12-hour low-temperature treatment at 4°C.

Use Cases

• Analyzing gene expression patterns related to chlorophyll biosynthesis and photosynthesis under cold stress based on mentioned genes like HEMA1 and POR1.
• Studying osmotic adjustment mechanisms based on proline accumulation data and associated genes like PAP1 and ProT.
• Investigating antioxidant defense systems based on measurements of superoxide dismutase and catalase activities.
• Examining the relationship between cold stress and abscisic acid (ABA) regulation based on biosynthetic gene (e.g., NCED1) expression and ABA content measurements.

Strengths

• Data is associated with a detailed, peer-reviewed-style methodological description of the experimental conditions, including a 12-hour treatment at 4°C.
• The dataset is licensed under CC-BY-4.0, allowing for broad reuse and sharing.

Limitations

• The dataset is a 3.7 MB DOCX file; the structure and format of the actual data tables are unknown and require inspection after download.
• Row count and column-level documentation are absent, limiting pre-download assessment of data scale and semantics.
