| Research Abstract |
To analyze the regulatory mechanism of patterned deposition of secondary cell walls in xylem vessels, I focused on the function of MIDD1, which interacts with both plasma membrane and cortical microtubules. I found that ROP GTPase is locally activated to recruit MIDD1 at the plasma membrane, which results in disassembly of cortical microtubules for formation of secondary cell wall pits. I also found that a mutual inhibitory interaction between ROP GTPase and cortical microtubules via MIDD1 induces the distinct pattern of secondary cell walls.
