Key Findings
- In space, Arabidopsis plants showed changes in DNA methylation, which affects gene activity and stress response
- A mutant Arabidopsis with a disrupted epigenetic gene had more pronounced methylation changes, struggling more in space
- These findings suggest that controlling plant epigenetics is key for adapting them to space environments
