Spaceflight adaptation requires organ specific alterations in the proteomes of Arabidopsis

Published by Open Science Data Repository | National Aeronautics and Space Administration | Metadata Last Checked: August 31, 2025 | Last Modified: 2025-08-21
Life in spaceflight demonstrates remarkable adaptive processes within the specialized environments of space vehicles which are subject to the myriad of attending and unique environmental issues associated with orbital trajectories. To examine the adaptive processes that occur in plants in space, leaves and roots from Arabidopsis seedlings that were grown from seed for 12 days on the International Space Station and preserved on orbit in RNAlater were returned to earth and analyzed using iTRAQ broad scale proteomics procedures.
