Bacillus subtilis Transcriptional Responses at 5 kPa vs 101 kPa

Two Bacillus subtilis strains, WN624 and WN1106, are compared across 4 pressure comparisons. The experiment probes transcriptional responses at low pressure (5 kPa) versus standard pressure (101 kPa), with WN1106 being a 5 kPa-evolved strain. The dataset was published by the National Aeronautics and Space Administration and last updated in March 2026.

Use Cases

• Identify gene expression differences between low and standard atmospheric pressure based on the transcriptional response data.
• Compare the fitness and adaptation of an evolved strain versus its ancestor based on the WN1106 and WN624 comparison.
• Model bacterial transcriptional networks under space-relevant conditions based on the low-pressure growth experiment.

Strengths

• Data originates from the National Aeronautics and Space Administration, a recognized authority in space-related research.
• The experimental design includes 4 distinct pressure comparisons for controlled analysis.

Limitations

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