Research Concept
植物は置かれた環境に順応するため器官間で情報をやりとりし、形態形成と代謝システムを個体レベルで最適化しています(植物最適行動)。地球上の生命のほとんどが植物の同化生産(食料生産)に依存していることから、「植物最適行動」の仕組みを解明することは、農学・生命科学の中心課題の1つといえます。本研究ユニットでは「長距離情報輸送分子の機能研究」を発展させ、植物最適行動統御研究の世界拠点を築くとともに、これまでにない植物機能制御技術の確立を目指します。
Plants have elaborate response systems to nutritional condition to optimize their growth at whole-body level (plant optimal behavior). As an example, plants adjust growth balance of shoot and root to nitrogen supply in which they germinated. Due to the fact that most of life on Earth depends on assimilation production (food production) of plants, elucidating the mechanisms of "plant optimal behavior" is one of the central issues of agriculture and life science. This research unit aims to elucidate molecular mechanisms underlying optimized plant behavior in response to nitrogen availability specially focusing on a role of signaling molecules. This unit starts as a small group, but we will expand collaborative network to build a center of excellence in plant optimal behavior research. Our research results would be applied to molecular bleeding toward low-input/stable output agriculture.
