Abstract Plant development and morphogenesis rely on tight spatiotemporal regulation of cell growth, which in turn depends on the acidity of the cell wall1,2. According to the widely accepted acid growth theory, auxin promotes shoot cell expansion by acidifying the apoplast via activation of AHA proton pumps3. Nonetheless, how exactly auxin signalling and cell wall acidity feed into the developmental zonation of cell expansion in the roots remains unresolved.
