Sweet Potato DNA Methylation Patterns from Tissue Culture and Drought Stress

Bisulfite sequencing data reveals genotype-specific DNA methylation responses to tissue culture and drought stress in sweetpotato. Ajay Dhungana published the dataset on figshare in May 2026. The 21.6 KB Excel file likely contains statistical results comparing epigenetic stability across propagation methods.

Use Cases

• Compare epigenetic stability between meristem-initiated and conventional nodal cultures based on methylation pattern analysis.
• Analyze genotype-dependent methylation remodeling under drought stress based on bisulfite sequencing results.
• Investigate cumulative in vitro stress effects on DNA methylation enhancement during prolonged tissue culture.
• Evaluate the feasibility of long-term in vitro propagation for maintaining epigenetic stability based on clonal subculture data.

Strengths

• Data is derived from bisulfite sequencing, a specific epigenetic analysis technique.
• Focuses on commercial varieties and half-sib progenies, providing a comparative genetic context.
• License is CC-BY-4.0, allowing for open reuse and redistribution.

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 21.6 KB, indicating a very limited scope and likely summary-level results rather than raw sequencing data.
