The central vasculature of plant roots is protected by a hydrophobic ring of endodermal cells that are enclosed by lamellae of suberin. Barberon et al. demonstrate that endodermal suberization plasticity facilitates ion homeostasis, with antithetical regulation of suberin deposition and degradation by the phytohormones abscisic acid and ethylene.
