Sweet Potato DNA Methylation Patterns Under Tissue Culture and Drought Stress

A 21.6 KB Excel dataset from figshare, last updated May 5, 2026, by author Ajay Dhungana. It contains results from a study using bisulfite sequencing to analyze genotype-specific DNA methylation responses to tissue culture propagation and drought stress in commercial sweetpotato varieties and half-sib progenies. The study revealed stable methylation during tissue culture but unpredictable, variety-dependent remodeling under drought.

Use Cases

• Compare epigenetic stability between meristem-initiated and conventional nodal tissue culture methods based on the described methylation patterns.
• Analyze genotype-dependent epigenetic plasticity in response to drought stress based on the described methylation shifts.
• Investigate the cumulative effect of in vitro stress on DNA methylation enhancement during prolonged tissue culture as mentioned in the description.
• Study the feasibility of long-term in vitro propagation for maintaining genetic stability based on the described consistent stability in clonal subculture.

Strengths

• Dataset is openly licensed under CC-BY-4.0.
• Study design is clearly described, focusing on bisulfite sequencing of commercial varieties and half-sib progenies under specific conditions.
• File size is 21.6 KB, indicating a focused and likely manageable dataset.

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 small (21.6 KB), indicating limited scope.
