CmHDZ Gene Family in Chinese Chestnut: Identification and Stress Expression Patterns

25 CmHDZ genes were identified from the Chinese chestnut (Castanea mollissima) genome by author Xiurong Xu. The dataset includes evolutionary classification into four subfamilies, collinearity analysis with other plants, and expression patterns under abiotic stress. It was last updated on 2026-04-30 and is shared under a CC-BY-4.0 license.

Use Cases

• Identifying candidate stress-resistance genes based on promoter analysis for hormone and stress response elements.
• Studying gene family evolution and synteny based on collinearity analysis with species like Arabidopsis thaliana, rice, and maize.
• Analyzing tissue-specific gene expression patterns under different abiotic stress conditions like shading, low-temperature, and high-temperature treatments.

Strengths

• Contains data on 25 identified CmHDZ genes with detailed subfamily classification (HDZ I, II, III, IV).
• Includes results from multiple analyses: evolutionary classification, subcellular localization prediction, collinearity, and cis-acting element prediction.
• Expression data is validated by quantitative analysis, confirming the reliability of the transcriptome data.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is small (89.1 KB), indicating limited scope and likely a single, focused table of results.
