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

Xiurong Xu identified 25 CmHDZ transcription factor genes in the Chinese chestnut (Castanea mollissima) genome. The dataset includes evolutionary classification, collinearity analysis with other plants, and expression patterns under abiotic stress treatments like shading and temperature extremes. It was uploaded to figshare on 2026-04-30 under a CC-BY-4.0 license.

Use Cases

• Identify candidate stress-resistance genes based on promoter analysis for hormone and stress response elements.
• Study gene family evolution and homology based on the classification of 25 genes into four HDZ subfamilies.
• Analyze tissue-specific expression patterns under different abiotic stresses, such as low-temperature and high-temperature treatments.
• Validate transcriptome data reliability using quantitative analysis results mentioned for genes like CmHDZ15.

Strengths

• Contains data on 25 identified CmHDZ genes with specific subfamily counts: HDZ I (13), II (7), III (4), and IV (1).
• Includes results from multiple analyses: evolutionary classification, collinearity (e.g., up to 34 gene pairs with Arabidopsis), and cis-acting element prediction for all 25 genes.
• Expression data is linked to specific experimental treatments like shading, low-temperature, and high-temperature, with CmHDZ15 highlighted.

Limitations

• Row count and column-level documentation are unknown, which may limit suitability assessment.
• The dataset is very small at 9.0 KB, indicating limited scope.
• Description metadata is limited; actual data quality and structure require manual inspection after download.
