Corynebacterium glutamicum Compendium: 927 Transcriptional Profiles for 3,047 Genes

Forschungszentrum Jülich presents a manually curated compendium of 927 microarray-based transcriptional profiles for the industrial microorganism Corynebacterium glutamicum. The data captures genome-wide expression changes for 3,047 annotated genes across wild-type and engineered strains under various environmental conditions or genetic modifications. Replicates were combined into 304 microarray sets across six categories for differential gene expression analysis.

Use Cases

• Analyzing differential gene expression based on the 304 categorized microarray sets.
• Studying transcriptional regulation in response to environmental conditions described in the compendium.
• Identifying gene expression patterns for rational strain construction of microbial cell factories.
• Clustering gene expression profiles based on the hierarchical analysis mentioned.

Strengths

• Contains 927 manually curated transcriptional profiles, indicating a substantial collection.
• Covers genome-wide expression data for all 3,047 annotated genes in Corynebacterium glutamicum.
• Data is organized into 304 microarray sets across six defined categories for structured analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
