Abstract
The plant plasma membrane H+-ATPase is an electrogenic H+-pump transporting H+ from the cytosol to the cell wall. This enzyme has several pivotal roles in the physiology of plants (Palmgren, 1997). The H+-gradient generated across the plasma membrane provides energy for nutrient uptake and osmotic adaptation. The pump plays an obvious role in regulation of cytoplasmic pH. The lowered pH of the cell wall as a result of H+ extrusion seems to be required for plant cell elongation. Furthermore, H+ pump activity controls opening and closure of the stomatal apparatus allowing for water loss and CO2 uptake into leaves.
