Orthologous Gene Groups and Expression Values Across Four Vertebrate Species

Orthologous Gene Groups (OGGs) and their expression values for four vertebrate reference species: mammals (Rattus norvegicus), birds (Gallus gallus), frogs (Xenopus tropicalis), and fishes (Oreochromis niloticus). The dataset, created by Rebecca Young and harvested from the Texas Data Repository, was last updated on March 18, 2024. It includes files for OGGs identified by OrthoMCL software, a subset of groups present in all four species, and gene expression counts derived from bwa mapping.

Use Cases

• Identify conserved gene families across vertebrate lineages based on Orthologous Gene Groups (OGGs).
• Analyze cross-species gene expression patterns using the provided mapping count data.
• Study evolutionary relationships by examining the subset of OGGs common to all four reference species.

Strengths

• Includes data from four distinct vertebrate classes, enabling broad comparative analysis.
• Provides a defined subset of orthologous groups present in all species, which may represent highly conserved genes.
• Last updated on March 18, 2024, indicating recent maintenance.

Limitations

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