Tobacco Phytoene Synthase Genes: Expression, Phylogeny, and Cold Stress Response

A dataset from figshare containing analysis of five identified tobacco phytoene synthase (NtPSY) genes. The data includes results from phylogenetic, synteny, and transcriptomic expression analyses, with specific findings on NtPSY1's role in carotenoid accumulation and cold stress tolerance. The dataset was authored by Xiaoxu Li and last updated on April 10, 2026.

Use Cases

• Phylogenetic classification of phytoene synthase genes based on the reported subgroup analysis.
• Studying gene duplication events and family expansion using the identified synteny data.
• Analyzing gene expression patterns under different conditions from the transcriptomic results.
• Investigating the link between carotenoid biosynthesis and cold stress tolerance based on the NtPSY1 overexpression assays.
• Modeling the relationship between phytoene synthase activity and strigolactone biosynthesis pathways.

Strengths

• Analysis is based on the latest genome annotation for tobacco.
• Integrates results from phylogenetic, synteny, and expression analyses.
• Includes specific experimental validation for NtPSY1 function in cold tolerance and carotenoid accumulation.
• Published under a CC-BY-4.0 license for open reuse.

Limitations

• Row count and specific column-level documentation are unknown.
• The dataset is small at 467.6 KB, indicating limited scope.
• Data quality and field semantics must be inferred after download.
