Arabidopsis Gene Expression in Spaceflight: Arg1 Knockout vs. Wild Type

Transcriptome profiles compare wild-type and ARG1 knockout Arabidopsis thaliana cells grown on the SpaceX CRS-2 mission and on the ground. The data includes differentially expressed genes identified between spaceflight and ground environments and between the two genotypes. NASA produced this dataset as part of the BRIC17 mission's Cellular Expression Logic experiment.

Use Cases

• Identify genes involved in plant cell adaptation to spaceflight based on differential expression analysis.
• Study the role of the Altered response to gravity-1 (Arg1) gene by comparing knockout and wild-type profiles.
• Analyze genotype-specific physiological adaptation strategies from unique gene expression patterns.

Strengths

• Data originates from a controlled spaceflight experiment on the SpaceX CRS-2 mission.
• Analysis compares two distinct genotypes (wild type and ARG1 KO) across two environments (space and ground).

Limitations

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