APEX03-2: Arabidopsis DNA Methylation Patterns from ISS Spaceflight

Arabidopsis thaliana plants were germinated and grown on the International Space Station (ISS) to investigate molecular mechanisms for altered growth habits in microgravity. The APEX03-2 (TAGES-ISA) experiment addresses growth and molecular changes using genetic tools, focusing on root structure and cell wall remodeling. Data was produced by the National Aeronautics and Space Administration (NASA) and last updated in March 2026.

Use Cases

• Identify epigenetic markers associated with spaceflight stress based on methylome data.
• Compare root structure and growth patterns between spaceflight and terrestrial control plants.
• Analyze gene expression changes related to cell wall remodeling in microgravity.
• Model molecular biological responses to inform future long-duration space exploration missions.

Strengths

• Data originates from a controlled NASA spaceflight experiment (APEX03-2/TAGES-ISA) on the ISS.
• Project aims to answer fundamental questions regarding root structure and cell wall remodeling.

Limitations

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