Development of environmental-stress-tolerant plant by modification of membrane trafficking pathways

　There are many single membrane-bounded organelles in plant cells, which are connected each other by membrane trafficking pathways. We have recently demonstrated that the plant-unique membrane trafficking pathway plays distinctive roles in responses to environmental stresses including the salinity stress. In this research project, we carry out studies to unveil the molecular mechanism of this trafficking pathway with a special focus on stress tolerance. We will also attempt to develop environmental-stress-tolerant plants by modifying the activity of this trafficking pathway, which will lead to improvement in biomass production and carbon fixation.
