Outline of Final Research Achievements

This study addressed the functions of plant-unique glycosphingolipids. Sphingolipidomic and genetic approaches determined plant species- and tissue-dependent variation of oligosaccharide types and the responsible enzymes GMT1 and GINT1. Analyses of the mutants revealed sugar type-specific functions, such as enlarged seed size and accumulated seed lipid and protein contents in gint1 mutant. Genetic modification of the hydrophobic ceramide moieties, showing lipid class-dependent diversity, demonstrated that glycosphingolipids contribute to tolerance to aluminum toxicity in plants.

Academic Significance and Societal Importance of the Research Achievements

スフィンゴ脂質は真核生物に普遍的な存在であるが、その構造は生物ごとに多彩な進化を遂げており、それぞれに特有の機能をもつと考えられる。本研究は植物に固有なスフィンゴ糖脂質の機能の一端を解明し、さらにその構造を遺伝子レベルで人為改変することに世界で初めて成功した。これは、本研究で明らかにした種子生産性や酸性土壌のアルミニウム耐性など、植物の有用機能を向上させる新たな分子育種技術として期待される。
