Outline of Research at the Start

植物が同じ種内でもストレス耐性を持つ植物と持たない植物に分かれてきた進化的要因や、その背景でどんな遺伝子が働いているのかに関しては多くが不明である。そこで本研究では、シロイヌナズナに見られる浸透圧および高温耐性の遺伝的多様性から植物のストレス適応メカニズムを理解することを目的に、多様性を決定する鍵遺伝子の同定、および鍵遺伝子を中心とする耐性メカニズムの解明を目指す。さらに同定遺伝子などのイネやトマトへの応用を進めることで、農資源の機能性向上を目指す。

Outline of Final Research Achievements

To elucidate the mechanisms underlying natural variation in osmotic or heat stress tolerance among Arabidopsis thaliana accessions, we (1) analyzed acquired osmotolerance defective (aod) mutants, (2) identified loci responsible for the difference in long-term among accessions, and (3) isolated and analyzed sensitive to long-term heat (sloh) mutants. We have elucidated the mechanisms of osmotic or heat stress response in Arabidopsis by identifying the genes responsible for mutants that are hypersensitive to osmotic or heat stress.

Academic Significance and Societal Importance of the Research Achievements

地球温暖化の影響により世界中で干ばつ(乾燥)・塩害・日照り(高温)が多発しており、農業生産に甚大な被害が生じている。本研究でそれらのストレス耐性に重要な遺伝子に加えて、見出した遺伝子の1つは植物の様々な環境ストレス耐性を向上させることから、干ばつや温度上昇など幅広い環境変動に適応する作物育種への応用が期待される。
