Aquaporins are channel proteins present in the plasma membrane and most of intracellular compartments of plant cells. This review focuses on recent insights into the cellular function of plant aquaporins, with an emphasis on the subfamily of Plasma membrane Intrinsic Proteins (PIPs). Whereas PIPs mostly serve as water channels, novel functions associated with their ability to transport carbon dioxide and hydrogen peroxide are emerging. Phosphorylation of PIPs was found to play a central role in the mechanisms that determine their gating and subcellular dynamics. Dynamic tracking of single aquaporin molecules in native plant membranes and the search for cell signaling intermediates acting upstream of aquaporins are now used to dissect their cellular regulation by hormonal and environmental stimuli.
