Plant Vasculature: Selective Membrane-to-Microtubule Tethering Patterns the Xylem Cell Wall

Plant Vasculature: Selective Membrane-to-Microtubule Tethering Patterns the Xylem Cell Wall
Yrjö Helariutta, Lothar Kalmbach, Matthieu Bourdon

Summary

To introduce pits into a cell wall, plants depolymerize cortical microtubules, which prevents subsequent secondary cell wall thickening. A newly identified protein tethers microtubules to the plasma membrane and contains this breakdown to defined regions, thereby shaping these holes.
