Genomic Diversification and Adaptive Convergence in Aging E. Coli Colonies

Supplementary data from a study on Escherichia coli genomic evolution. The dataset includes a list of mutated genes from strains isolated from 3-week-old colonies, with mutation types and strain identifiers. It also contains transcriptomic fold-change data and results from a GO biological process enrichment analysis of these mutated genes.

Use Cases

• Identify genes under selection during colony aging based on mutation data.
• Analyze the relationship between gene mutations and RpoS regulon membership.
• Investigate gene expression changes during colony maturation using log2 fold-change data.
• Perform functional enrichment analysis based on the GO biological process results.

Strengths

• Data is directly linked to a specific published study on E. coli evolution.
• Includes multiple data types: mutation lists, transcriptomic fold changes, and GO enrichment results.
• File size is 22.3 KB, indicating a focused and likely manageable dataset.

Limitations

• Row and column counts are unknown, making it difficult to assess the dataset's scale and structure.
• Column-level documentation is absent; field semantics must be inferred from the description.
• The dataset is a supplementary file; its comprehensiveness depends on the scope of the original study.
