However, only limited information has been obtained for this graviresponse. To clarify the nature and mechanisms of gravity resistance, we have organized a working group, consisting 16 members. Here, we report the activity of this working group in the current year, and propose the strategies for space experiments to understand gravity resistance in plants. By hypergravity experiments using different plant materials, we have found that not only seedlings, but also calli and cultured cells show gravity resistance response. We have also studied the details of the processes of gravity resistance; signal perception, transformation and transduction of a perceived signal, and response. We need to clarify the nature and the details of gravity resistance by future space experiments. For this purpose, we should establish the procedure of on-site analyses on orbit with new instruments and suitable plant materials such as mutants., 資料番号: AA0063349107}, pages = {375--378}, 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/ISAS)}, title = {植物の抗重力反応解明}, year = {2007} }
