Arabidopsis Transcriptome Responses to Hypobaric Stress Under Controlled Atmospheres

NASA conducted a controlled experiment comparing whole transcriptomes of Arabidopsis seedlings grown in ambient atmospheric conditions to those exposed to five different low-pressure and varying oxygen atmospheres for 24 hours. The study used 5- and 10-day-old plants to evaluate age-dependent responses, with gene expression profiles analyzed from both roots and shoots. The data was last updated on 2026-03-13.

Use Cases

• Identify gene expression changes in response to low atmospheric pressure based on transcriptome comparisons.
• Study the interaction between hypobaric and hypoxic stress based on controlled variations in pressure and oxygen partial pressure.
• Analyze age-dependent stress responses in plants based on experiments with 5- and 10-day-old Arabidopsis seedlings.
• Compare tissue-specific (root vs. shoot) transcriptional regulation under hypobaric conditions.

Strengths

• Experiment includes five distinct atmospheric conditions for controlled comparison of pressure and oxygen effects.
• Data includes both root and shoot tissue samples, allowing for tissue-specific analysis.
• Study design evaluates age-dependent responses by including 5-day-old and 10-day-old plants.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is provided in a BIN file format, which may require specific tools for access and analysis.
