Determination of H+-ATPase Activity in Arabidopsis Guard Cell Protoplasts through H+-pumping Measurement and H+-ATPase Quantification [PDF]
The opening of stomata in plants in response to blue light is driven by the plasma membrane H+-ATPase in guard cells. To evaluate the activation of the H+-ATPase in vivo, we can use H+-pumping by guard cells in response to blue light and fusicoccin.

SCaBP3/CBL7 negatively regulates the plasma membrane H+-ATPase and modulates hypocotyl elongation in Arabidopsis [PDF]
The regulation of hypocotyl elongation is an important process in plant growth and development and depends on the activity of the plasma membrane (PM) H+-ATPase.

Screening of protonstatin-1 (PS-1) analogs for improved inhibitors of plant plasma membrane H+-ATPase activity [PDF]
We previously identified protonstatin-1 (PS-1) as a selective inhibitor of plasma membrane H+-ATPase (PM H+-ATPase) activity and used it as a tool to validate the chemiosmotic model for polar auxin transport.

The Oligomeric State of the Plasma Membrane H+-ATPase from Kluyveromyces lactis [PDF]
The plasma membrane H+-ATPase was purified from the yeast K. lactis. The oligomeric state of the H+-ATPase is not known. Size exclusion chromatography displayed two macromolecular assembly states (MASs) of different sizes for the solubilized enzyme. Blue

Promotion and Upregulation of a Plasma Membrane Proton-ATPase Strategy: Principles and Applications
Plasma membrane proton-ATPase (PM H+-ATPase) is a primary H+ transporter that consumes ATP in vivo and is a limiting factor in the blue light-induced stomatal opening signaling pathway.

Enhanced expression of vacuolar H+-ATPase subunit E in the roots is associated with the adaptation of Broussonetia papyrifera to salt stress. [PDF]
Vacuolar H(+)-ATPase (V-H(+)-ATPase) may play a pivotal role in maintenance of ion homeostasis inside plant cells. In the present study, the expression of V-H(+)-ATPase genes was analyzed in the roots and leaves of a woody plant, Broussonetia papyrifera,
