Sweet Potato DNA Methylation Patterns Under Tissue Culture and Drought Stress

A 2026 study by Ajay Dhungana investigates DNA methylation patterns in sweetpotato. The research uses bisulfite sequencing to analyze epigenetic stability across commercial varieties and half-sib progenies under different propagation methods and drought stress. The dataset is a 2.2 MB document shared under a CC-BY-4.0 license.

Use Cases

• Compare genotype-specific epigenetic plasticity based on DNA methylation responses to tissue culture.
• Analyze epigenetic reprogramming patterns based on methylation remodeling induced by drought stress.
• Assess the feasibility of long-term in vitro propagation for maintaining epigenetic stability based on methylation pattern consistency.

Strengths

• Dataset is based on bisulfite sequencing, a standard method for DNA methylation analysis.
• The study compares multiple factors: different propagation methods, drought stress, and multiple sweetpotato genotypes.
• Findings include specific observations, such as methylation enhancement from prolonged tissue culture and pronounced shifts in greenhouse mother plants.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The primary data file is a DOCX document, which may require extraction or conversion for computational analysis.
