Our collaborative works will bring about hypotheses on the molecular mechanisms underlying plant responses to gravity, which will be further verified by spaceflight experiments. This approach will also lead to the establishment of technology useful for controlling plant growth and development in space. We have continued our studies to reveal mechanisms underlying graviperception and its signal transduction in plants by using gravitropic mutants, and found various genes and molecules responsible for the mutations. Also, we have studied the gravity-influenced growth and development of plants; namely, gravimorphogenesis of cucumber seedlings, shoot circumnutation, and hydrotropism in seedling roots. The results obtained suggested molecular cascades for graviresponse and molecular networks for the interactions among the gravity-influenced phenomena. Based on these accomplishments, we are attempting to establish models and hypotheses to be verified by spaceflight experiments. Some of the subjects being dealt in this project are to be flown in this year. Currently, we are preparing to propose another spaceflight experiment on circumnutation and its relationship to graviresponse in plants., 共催: 日本学術会議, 著者人数: 17人, joint hosting: The Science Council of Japan, 資料番号: AA0064730068}, 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 = {フロンティア生物の戦略: 植物の成長と重力受容システム}, volume = {26}, year = {2010} }
