Transcriptomics of Etiolated Arabidopsis Seedlings in Microgravity

Gene expression profiles of two-week-old etiolated Arabidopsis seedlings from the BRIC16 space flight experiment. The dataset compares wild-type and act2-3 mutant plants grown under microgravity with ground controls. It was produced by the National Aeronautics and Space Administration and last updated in March 2026.

Use Cases

• Identify genes differentially expressed in response to microgravity based on the comparison of spaceflight and ground control samples.
• Analyze the role of the ACT2 gene in gravity response pathways based on the inclusion of act2-3 mutant plants.
• Study the combined effects of microgravity and etiolation (dark growth) on plant development based on the seedling condition described.

Strengths

• Data originates from a controlled spaceflight experiment (BRIC16) conducted by NASA.
• Includes comparisons between two genetic variants (wild-type and act2-3 mutant) and two environmental conditions (microgravity and ground control).

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 specialized tools for access and analysis.
