Outline of Final Research Achievements	To understand the relationship between polyamine and senescence in plants, I analyzed internal polyamine levels and effect of polyamine treatment in various horticultural crops during senescence. Then, it was found that quality of some crops was improved by exogenous polyamine treatment. In addition, uncommon minor polyamine and it biosynthetic pathway was identified.
Academic Significance and Societal Importance of the Research Achievements	本研究では、収穫後の農作物の保存過程において減少するポリアミン類を外から加える事で、品質低下の指標となる老化を抑制する効果がある事を突き止めた。ポリアミンは人を含む全ての生物の生命維持に必須の化合物である事から、常に我々の体内においても作られている。つまり、本研究成果を応用する事で、人体に悪影響を及ぼさない分子を農作物の品質保持や高品質化に利用できる大きな可能性が期待できる。
