  abstract = {{A}quaporins are membrane channels that facilitate water movement across cell membranes. {I}n plants, aquaporins contribute to water relations. {H}ere, we establish a new link between aquaporin-dependent tissue hydraulics and auxin-regulated root development in {A}rabidopsis thaliana. {W}e report that most aquaporin genes are repressed during lateral root formation and by exogenous auxin treatment. {A}uxin reduces root hydraulic conductivity both at the cell and whole-organ levels. {T}he highly expressed aquaporin {PIP}2;1 is progressively excluded from the site of the auxin response maximum in lateral root primordia ({LRP}) whilst being maintained at their base and underlying vascular tissues. {M}odelling predicts that the positive and negative perturbations of {PIP}2;1 expression alter water flow into {LRP}, thereby slowing lateral root emergence ({LRE}). {C}onsistent with this mechanism, pip2;1 mutants and {PIP}2;1-overexpressing lines exhibit delayed {LRE}. {W}e conclude that auxin promotes {LRE} by regulating the spatial and temporal distribution of aquaporin-dependent root tissue water transport.},
