植物体内における養分の分配は作物の生産量や食味に大きく関わるため，養分分配に関する知見は農業の発展に重要である。一方で植物体内での元素の輸送・蓄積などの動態は常に変化するため解析が難しく，元素の動態や分配制御のメカニズムはいまだ不明な点が多い。これらのメカニズムを解明するにあたり，植物を生きたままの状態で解析することが有効であり，RIを用いたライブイメージングは強力なツールである。
Distribution of nutrients in plants has a significant impact on crop yield and taste; hence, a knowledge of plant-nutrient relationships is important for developing crop production strategies. The dynamics of element transport and accumulation in plants can be difficult to analyze because they are constantly changing, and the mechanisms underlying element dynamics and distribution control remain unknown. Radioisotope imaging in live plants can be useful for the analyses of changes in element transport and accumulation.
Key words: plant nutrition; real-time radioisotope imaging system (RRIS); Imaging Plate; radioisotope tracer; photosynthesis
