| Open AccessStructural basis for high selectivity of a rice silicon channel Lsi1
The rice Lsi1 aquaporin mediates uptake of silicic acid via the roots. Here the authors show the crystal structure of rice Lsi1 and characterize a unique five residue hydrophilic selectivity filter providing a structural basis for the highly selective activity of Lsi1 in Si uptake.
