ROS signaling and rapid phase-specific gene regulation underlie acute stress response
Changes in gravity and flight phase (e.g., microgravity at F3) rapidly activate ROS-related pathways (including upregulation of LHC genes and downregulation of GST, P450, and histones), mirroring broader abiotic stress responses and indicating that plants initiate space adaptation in minutes.
