Herbaspirillum rubrisubalbicans M1 Gene Expression and PHB Metabolism Data

1.1 MB of data from figshare details the role of transcriptional regulator Hrubri_0242 in Herbaspirillum rubrisubalbicans M1. The dataset, authored by Roxana Beatriz Ribeiro Chaves and last updated in June 2026, links nitrogen response to polyhydroxybutyrate metabolism and swarming motility.

Use Cases

• Modeling the relationship between nitrogen availability and PHB metabolism based on gene expression data.
• Analyzing the coordinated regulation of PHB synthesis (phaC1), stabilization (phaP1, phaP2), and degradation (phaZ1, phaZ2) genes.
• Investigating the link between transcriptional regulation and physiological traits like swarming motility mentioned in the results.
• Comparing PHB accumulation and consumption cycles between wild-type and mutant bacterial strains under different nutrient conditions.

Strengths

• Data is derived from multiple experimental methods including quantitative GC-FID, fluorescence microscopy, and gene expression analysis.
• License is CC-BY-4.0, permitting broad reuse with attribution.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The primary data file is a 1.1 MB DOCX document, which may require extraction of underlying data.
