| Outline of Final Research Achievements |
We conducted the “Auxin Transport” space experiment in the International Space Station (ISS), with the principal objective of the growth and development of etiolated pea (Pisum sativum L. cv Alaska) and maize (Zea mays L. cv Golden Cross Bantam) seedlings under true microgravity conditions in space in relation to plant hormone dynamics, especially auxin. Etiolated pea and maize seedlings grown under microgravity conditions in space showed automorphogenesis. Polar auxin transport and its related membrane proteins were substantially affected by microgravity conditions in space. These results strongly suggest that adequate polar auxin transport is essential for gravitropic response in plants. Possible mechanisms affecting polar auxin transport in etiolated pea and maize seedlings grown under microgravity conditions in space are also proposed.
