• Note (General): 宇宙実験STS-95(宇宙輸送システム)のBRIC-AUX(キャニスタ中での生物学的研究-オーキシン)において遮光条件下でのマメおよびトウモロコシ実生の生長と発生、および茎におけるオーキシン極性移動に対する微小重力の影響を分析した。微小重力は実生の生長と発生に強く影響し、実生の傾き・屈曲・生長抑制を観察した。宇宙で発芽・生長したマメ上胚軸第3節間およびトウモロコシ子葉鞘頂端部において、細胞壁の伸展成長は非常に少なかった。オーキシン極性移動の活性は、マメ実生茎部第2節間ではきわめて抑制されるが、トウモロコシ子葉鞘茎部では非常に促進された。以上の結果は、植物の生長や発生と同様にオーキシン極性移動が地球上では重力の制御下にあることを強く示唆する。; The principal objective of the space experiment, BRIC-AUX (Biological Research In Canisters-Auxin) on STS-95 (Space Transportation System), was the integrated analysis of the growth and development of etiolated pea and maize seedlings in space, and the effect of microgravity conditions in space on auxin polar transport in the segments. Microgravity conditions in space strongly affected the growth and development of etiolated pea and maize seedlings. Etiolated pea and maize seedlings were leaned and curved during space flight, respectively. Finally the growth inhibition of these seedlings was also observed. Roots of some pea seedlings grew toward the aerial space of Plant Growth Chamber. Extensibilities of cell walls of the third internode of etiolated pea epicotyls and the top region of etiolated maize coleoptiles which were germinated and grown under microgravity conditions in space were significantly low. Activities of auxin polar transport in the second internode segments of etiolated pea seedlings and coleoptile segments of etiolated maize seedlings were significantly inhibited and extremely promoted, respectively, under microgravity conditions in space. These results strongly suggest that auxin polar transport as well as the growth and development of plants is controlled under gravity on the earth.; 資料番号: AA0003840001; レポート番号: NASDA-TMR-000004E
