title: CLASPing microtubules and auxin transport.
abstract: The role, if any, of microtubules in auxin transport is poorly understood in plant biology. In this issue of Developmental Cell, Ambrose et al. (2013) show that the microtubule binding protein CLASP regulates PIN2 auxin transporter trafficking and stability via Sorting Nexin1, a component of the retromer complex.
