In Arabidopsis, LZY proteins are involved in specifying the angle of root growth relative to the direction of gravity. Here the authors identify RLD1, a LZY-interacting protein that is recruited to the plasma membrane in a polar manner and is required to establish asymmetric auxin transport and set root angles.
