Sweet Potato DNA Methylation Patterns Under Tissue Culture and Drought Stress

A study by Ajay Dhungana, last updated in May 2026, investigates epigenetic stability in sweetpotato. The research uses bisulfite sequencing to analyze genotype-specific DNA methylation responses to tissue culture propagation and drought stress. The dataset is a 14.4 KB document summarizing findings on methylation patterns across commercial varieties and half-sib progenies.

Use Cases

• Compare epigenetic stability between meristem-initiated and conventional nodal tissue cultures based on the described propagation methods.
• Analyze genotype-dependent methylation remodeling in response to drought stress based on the described environmental interactions.
• Study cumulative in vitro stress effects on DNA methylation enhancement based on the mention of prolonged tissue culture.
• Investigate epigenetic reprogramming differences between greenhouse mother plants and in vitro subcultures based on the described stability observations.

Strengths

• Dataset is openly licensed under CC-BY-4.0.
• Description provides specific biological context regarding DNA methylation, tissue culture, and drought stress.
• Last update timestamp (2026-05-05 09:07:16) is provided.

Limitations

• Dataset is very small (14.4 KB), indicating limited scope, likely a summary document rather than raw sequencing data.
• Column-level documentation and sample data are unavailable; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for quantitative analysis.
