Regulation of secondary cell wall patterns

↓Click!!
Xylem cell differentiation involves temporal and spatial regulation of secondary cell wall deposition. To reveal the molecular mechanism underlying the secondary wall patterning, we newly established in vitro Arabidopsis xylem cell differentiation system and performed microarray analysis and live cell imaging. We identified a novel plasma membrane-anchored MAP, MIDD1 (Microtubule Depletion Domain 1), which controls depolymerization of cortical microtubules beneath pits lacking the secondary wall.
