Abstract
Michniewicz and colleagues identify a vacuolar transporter of the auxin precursor indole-3-butyric acid (IBA) that regulates lateral root branching, which they named TOB1. TOB1 is transcriptionally regulated by the phytohormone cytokinin to alter IBA contributions to the auxin pool, thus providing a mechanism for cytokinin to regulate lateral root development.
