| Outline of Final Research Achievements |
Based on our observation, we found that the GA-TGN gradually matures into the GI-TGN by acquiring components of the secretory pathway, and GI-TGN is required for pathogen-inducible protein secretion. In addition, quantitative proteomic approach demonstrated that the SYP4-VAMP721 secretory pathway mediates secretion of cell wall modification enzymes and is important for plant growth and extracellular defense against powdery mildew pathogens. Furthermore, we established long-time observation system under salt stress response.

| Academic Significance and Societal Importance of the Research Achievements |
トランスゴルジ網は細胞内タンパク質輸送の中心に位置する分岐点となる重要な区画であり、その機能がなくなると植物が病原菌に感染しやすくなることを発見した。トランゴルジ網の機能を制御することで、病気に強い植物の作出や、農薬の開発が期待される。
