Arabidopsis Gene Expression in Spaceflight vs. Ground, Col-0 and WS Genotypes

Gene expression profiles compare 4-day-old and 8-day-old Arabidopsis thaliana plants (Col-0 and WS genotypes) grown on the International Space Station versus on the ground. The data was produced by the National Aeronautics and Space Administration and last updated in March 2026. It captures differences in developmental strategies, including wax production, root development, and photosynthesis-related gene expression in a microgravity environment.

Use Cases

• Compare gene expression changes over time (4 to 8 days) based on the developmental stage data.
• Analyze the influence of genetic background on spaceflight adaptation based on the Col-0 and WS genotype comparison.
• Identify genes related to root system and anatomical structure development based on the overexpression patterns described.
• Study differential regulation of wax and suberin production pathways in a microgravity environment.
• Investigate photosynthesis-related gene expression unique to the WS genotype in spaceflight roots.

Strengths

• Data originates from a controlled spaceflight experiment conducted by the National Aeronautics and Space Administration.
• Description provides specific biological insights into developmental differences between two genotypes and two time points.
• Last updated 2026-03-13 19:28:27.561534; the metadata is recent.

Limitations

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