| Outline of Final Research Achievements |
Plant development largely depends on well-organized cell walls which determines the shape of each plant cell. I focused on how plant cortical microtubules and ROP GTPases spatially interact each other to determine the deposition pattern of cell walls in xylem vessels cells. I revealed that ROP GTPases mutually inhibit cortical microtubules through MIDD1-Kinesin-13A complex and possibly through BDR1, a novel protein of unknown function. I also found that VETH1 may mediate membrane trafficking of cell wall components along cortical microtubules. These findings may contribute to our further understanding of plant and plant cell morphogenesis.
