However, only limited information has been obtained for this graviresponse. We have organized a working group, consisting 13 members, to clarify the mechanism of gravity resistance. In this article, we report the current activity of this working group, and propose the strategies for space experiments to understand gravity resistance in plants. The process of gravity resistance consists of signal perception, transformation and transduction of a perceived signal, and response. We have shown the outline of the sequence of events leading to the development of mechanical resistance. We need to clarify the details of each step by future space experiments. For this purpose, we should design a plant cultivation chamber, applicable to not only model plants, but also other materials, including cultured cells. Also, it is required to develop some new analytical instruments, suitable for on-site analyses on orbit., 共催: 日本学術会議, 著者人数: 13人, Meeting sponsors: The Science Council of Japan, The Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (ISAS)(JAXA), 資料番号: AA0064113098}, publisher = {宇宙航空研究開発機構宇宙科学研究本部, Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)}, title = {植物の抗重力反応解明研究班WGの活動報告}, volume = {22}, year = {2006} }
