[Control of morphogenesis of woody plant by gravity on earth].
Using the weeping branch of Japanese flowering cherry tree and its woody stem of the seedling grown under simulated microgravity condition by three dimensional clinostat, it was elucidated that the morphogenesis of its secondary xylem supporting the plant itself to grow upward is seriously controlled by gravity on earth with a sedimentable amyloplast as its sensor. Space experiment of woody plant is expected to elucidate such problem.
