Cytoskeleton Dynamics Are Necessary for Early Events of Lateral Root Initiation in Arabidopsis (Current Biology)

Vilches Barro et al. image, perturb, and analyze the microtubule and actin cytoskeleton during the asymmetric radial expansion of lateral root founder cells. Reorganization of the cytoskeleton is necessary for this asymmetric expansion and intertwines with auxin signaling to grant a basic polarity to these cells.
