Background Hydrogen peroxide (H 2 O 2 ) is an important signaling compound that has
recently been identified as a new substrate for several members of the aquaporin superfamily in …

… Hachez and F. Chaumont, unpublished data). Plasma membrane delivery of ZmPIP2;5 or
AtPIP2;7 depends on its physical interaction with SYP121, and this mechanism is partially …

Aquaporins (AQPs) are ubiquitous membrane proteins whose identification, pioneered by
Peter Agre's team in the early nineties, provided a molecular basis for transmembrane water …

Aquaporins (AQPs) are an ancient family of channel proteins that transport water and neutral
solutes through a pore and are found in all eukaryotes and most prokaryotes. A comparison …

… in a greater increase in P f than did the expression of ZmPIP2;5 alone, but coexpression
of the ZmPIP1;1 and ZmPIP1;2 isoforms induced a P f increase, indicating that PIP1 isoform …

The effects of abscisic acid (ABA) on aquaporin content, root hydraulic conductivity (Lp r ),
whole plant hydraulic conductance, and leaf growth are controversial. We addressed these …

… A and D, Root tips; B and E, zone of cell elongation; C and F, elongated cells. … laevis

Accumulating evidence indicates that aquaporins play a key role in plant water relations. Plant
aquaporins are part of a large and highly divergent protein family that can be divided into …

… the membrane osmotic water permeability coefficient, P f . We previously showed that, in
Xenopus oocytes, ZmPIP1;2 and ZmPIP2;1 interact to increase the cell P f . Here, we report the …

… This correlates with changes in the membrane water permeability measured using a cell
pressure probe (C Hachez, W Fricke, F Chaumont, unpublished data). A diurnal oscillation in …
