Terpene Synthase Gene Expression Categories Across Plant Tissues

Plant terpene synthase (TPS) genes are categorized by phylogeny-based subfamily and assigned tissue-resolved expression levels (High, Medium, Low, Not Detected) for leaf, stem, and root tissues. The dataset provides specific quartile thresholds used to define these expression categories in normalized units. It was authored by Hinano Mizuno and last updated in March 2026.

Use Cases

• Compare expression categories (H/M/L/ND) across leaf, stem, and root tissues to identify tissue-specific TPS genes.
• Analyze the relationship between phylogeny-based subfamily assignment and the assigned expression patterns in different plant organs.
• Validate or apply the provided quartile thresholds (e.g., leaf Q25=0.15, Q75=5.56) to categorize new gene expression data from similar studies.

Strengths

• Expression categories are defined using clear, quantitative thresholds based on quartiles of replicate means.
• The dataset is focused on a specific biological context: terpene synthase genes in plants like Plectranthus hadiensis and Salvia rosmarinus.
• It was last updated in March 2026, indicating recent curation.

Limitations

• The dataset is very small at 10.8 KB, suggesting limited scope and a potentially small number of genes or observations.
• The exact number of rows (genes) and columns (features) is unknown, limiting assessment of its analytical scale.
• Expression data is categorical (H/M/L/ND) rather than continuous, which reduces granularity for quantitative analysis.
