Outline of Final Research Achievements

In order to increase the content of organosulfur compounds in plant, selection of plant (crop) with high levels of functional ingredients is important. To achieve the goal, we focused on absorption mechanisms of sulfur in Japanese heirloom vegetables of Brassicaceae family, which have many crops rich in organosulfur compounds. Using these plants which were cultivated under a gradient of sulfur concentration, we investigated the following points: 1) dry matter production; 2) sulfur content of plants; 3)expression levels of genes involved in sulfur absorption; 4) enzyme activity involved in sulfur assimilation. The results obtained in this study was published in the journal Soil Science and Plant Nutrition.

Academic Significance and Societal Importance of the Research Achievements

ヒトの健康への機能性を持つ成分の多くが植物の有機態硫黄化合物であることに着目し、これらの有機態硫黄化合物含有量を高め、摂食目的に適う機能性成分高含有野菜を育成を目指している。そこで、硫黄含有率が高い植物アブラナ科植物の、さらに優良形質が凝縮されていると考えられる伝統野菜を対象とし、硫黄供給量に比例して体内の硫黄含有量および有機態硫黄化合物が顕著に増大する野菜種を選抜した。さらに、その品種の硫黄吸収能と選抜した植物の硫黄の取り込みに関与する硫酸イオントランスポーター遺伝子の発現量との相関を調べ、植物の硫黄吸収と代謝制御に関する基礎的な知見を得た。
