Interplay between cortical microtubules and plasma membrane domains via the ROP11-MIDD1 complex. (A–C) MIDD1 mediates elimination of active ROP11 by cortical microtubules. (A) Cortical microtubules do not affect the localization of active (GTP-) ROP11. (B) Cortical microtubules eliminate active ROP11-truncated MIDD1 complex from the plasma membrane (truncated mutant lacking microtubule-binding domain). (C) Cortical microtubules eliminate the membrane–anchored truncated MIDD1. (D,E) Interplay between cortical microtubules and plasma membrane domains in xylem cells. (D) Cortical microtubules restrict the plasma membrane domain of active ROP11 generated by ROPGEF4. Inactive ROP11 is not affected by cortical microtubules, because there is no interaction with MIDD1. (E) Active ROP11-MIDD1-AtKinesin-13A complex associates with the microtubule growing into the domain and induces depolymerization.
