Maintaining Genetic Stability in Sweetpotato: Epigenetic Insights into Propagation and Drought Tolerance

This study provides a comprehensive analysis of methylation-mediated epigenetic modifications in response to in vitro and environmental (drought) stressors. we explore the boundaries of epigenetic plasticity and offer solutions for the long-term preservation of genetic fidelity by utilizing bisulfite sequencing in sweetpotato. Our findings reveal that epigenetic remodeling is highly genotype-dependent, offering new perspectives on methylome stability during prolonged tissue culture. This work fits the scope of Plant Science and Applied Plant Genomics section by contributing to the broader understanding of how epigenetic variations influence adaptation and stability in complex polyploid genomes. This is raw data used during the analysis for the given study. All datasets are in excel files.本研究针对体外培养与环境（干旱）胁迫下的甲基化介导表观遗传修饰展开系统性分析。本研究以甘薯为实验材料，采用亚硫酸氢盐测序（bisulfite sequencing）技术，探究表观遗传可塑性的边界，并为长期维持遗传保真度提供解决方案。研究结果表明，表观遗传重塑具有显著的基因型依赖性，为长期组织培养过程中的甲基化组（methylome）稳定性研究提供了全新视角。本研究有助于深化对表观遗传变异如何影响复杂多倍体基因组的适应性与稳定性的认知，契合《植物科学》与《应用植物基因组学》栏目的收录范围。 本研究分析过程中所使用的原始数据均为Excel格式文件，涵盖全部相关数据集。
