 note = {第22回宇宙利用シンポジウム(2006年1月17日-19日, 日本学術会議6階会議室 六本木、東京), The Twenty-second Space Utilization Symposium (January 17-19, 2006: Science Council of Japan, Roppongi, Tokyo, Japan), Plant shoots grow to the direction away from the gravity vector under 1 g conditions on earth. On the other hand, both true microgravity conditions in space (STS-95 space experiment) and simulated ones using a three-dimensional clinostat induced automorphosis together with significant inhibition of auxin polar transport in epicotyls of etiolated pea (Pisum sativum L. cv. Alaska) seedlings. In addition, automorphosis-like growth and development of etiolated pea seedlings were induced by the application of auxin polar transport inhibitors of HFCA (9-hydroxyfluorene-9-carboxylic acid), TIBA (2,3,5-triiodobenzoic acid) and NPA (N-(1-naphtyl)phthalamic acid), but not by that of PCIB (p-chlorophenoxyisobutyric acid), anti-auxin. The activities of auxin polar transport of pea epicotyls were also substantially suppressed by the application of inhibitors of auxin polar transport. In epicotyls of 2.5-dold etiolated pea seedlings, whose embryo axes in seeds were set in a horizontal position opposite to the direction of gravity, activities of auxin polar transport and gene expression of PsPIN1 encoding a facilitator protein of auxin polar transport were respectively asymmetrical in proximal and distal side of epicotyls, it being much higher in proximal side than in distal one. These results strongly support the idea that auxin polar transport is essentially required for graviresponse in early growth stage of etiolated pea seedlings., 共催: 日本学術会議, Meeting sponsors: The Science Council of Japan, The Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (ISAS)(JAXA), 資料番号: AA0064113092},
