Comparative Genomic Analysis of Stress-Associated Proteins in Peach and Other Plants

Nine stress-associated protein genes (PpSAP1-PpSAP9) were identified in the peach genome and analyzed for evolutionary relationships and stress responses. Wendou Zhang published this dataset on figshare in 2026, providing a framework for understanding gene family diversification. RNA-seq expression profiling demonstrated diverse transcriptional responses of these genes under drought, salinity, ethylene, and cold stress conditions.

Use Cases

• Identify candidate genes for improving peach stress resilience based on promoter cis-regulatory elements.
• Study evolutionary relationships of the SAP gene family across Rosaceae and more distant plant species.
• Analyze temporal expression patterns of specific PpSAP members under cold stress treatment.
• Investigate correlations between gene family structure and stress-responsive expression profiles.

Strengths

• Dataset provides the first genome-wide identification of the SAP gene family in peach (Prunus persica).
• Analysis includes promoter characterization revealing abundant stress and hormone-related cis-regulatory elements.
• Comparative evolutionary analysis spans multiple representative plant species, including Arabidopsis thaliana and Oryza sativa.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small (15.2 KB), indicating limited scope.
