Figure 1 Auxin transport-dependent regulation of halotropism. Schematic depiction of a root tip grown in a salt gradient. Cell-to-cell auxin transport (coloured arrows) defines asymmetric auxin signalling (green cells). High salt induces clathrin-dependent (grey C) PIN2 (depicted in red) internalisation at the lower root flank, ultimately providing for asymmetric auxin flux, differential organ growth and a directional halotropic growth response.
