EMF2 Calli: Epigenetic and Chromatin Changes During Arabidopsis Root Regeneration

Chang Liu's dataset from figshare, last updated May 2026, contains 2.7 GB of data on epigenetic and chromatin organization changes in Arabidopsis calli. It likely contains data from time-course analysis of root induction in emf2 mutants, including in situ Hi-C results. The data explores the role of H3K27me3 and three-dimensional chromatin interactions in gene regulation during plant organ regeneration.

Use Cases

• Analyzing changes in H3K27me3 histone modification patterns during callus root induction.
• Studying long-range chromatin interactions and three-dimensional organization in plant mutants.
• Investigating gene derepression patterns, particularly for floral development genes, in epigenetic mutants.
• Modeling the relationship between epigenetic marks, chromatin structure, and gene expression during plant regeneration.

Strengths

• Data size is 2.7 GB, indicating a substantial volume of raw experimental data.
• Includes data from a time-course analysis, suggesting a longitudinal experimental design.
• Focuses on a specific biological mutant (emf2) and process (root regeneration), providing targeted insights.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Description metadata is limited; actual data quality requires manual inspection after download.
