Abstract
The PIP1 subfamily of water channel proteins (aquaporins) constitute a bout 1% of the plasma membrane (PM) proteins from Arabidopsis thaliana leaves. Immunogold electron microscopy has confirmed their localizati on at the PM of mesophyll cells. Very high labeling density at PM inva ginations known as plasmalemmasomes was observed. Therefore, we sugges t that these subcellular structures are involved in water transport be tween the apoplast and the vacuole.
