This is the feature fundamentally important for plants to survive under various environmental conditions and to achieve efficient production of carbohydrates as primary energy of all organisms. To accomplish this task, plants respond to gravity for controlling their growth and development under terrestrial environment. For example, roots and stems display gravitropism. In addition, graviresponse has been implicated to be involved with circumnutation in plants. Another example of gravimorphogenesis is seen in the seedlings of cucurbitaceous plants; namely, unilateral positioning of a peg on the transition zone between the root and the hypocotyl. Plants also respond to various environmental cues, which interacts with graviresponse. However, mechanisms underlying the graviresponse and its relationship to other growth and development are not fully understood. Members of our working group have attempted to reveal the molecular mechanisms that essentially function in graviperception system and its involvement in various aspects of plant growth and development. We will further develop our research on the molecular dissections for obtaining general principles underlying the graviperception and its role in plant growth and development. Then, we will establish a model for spaceflight experiments to verify the hypothesis., 共催: 日本学術会議, 著者人数: 16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: AA0064113095}, 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 = {22}, year = {2006} }
