Abstract

Tonoplast H⁺-ATPase and H⁺-pyrophosphatase use energy released during hydrolysis of ATP and pyrophosphate. These enzymes are components of the proton signaling and pH-stat system of plant cells. A possible mechanism of cross-regulation of these enzymes during physiological changes in tested cells is still under discussion. This investigation is focused on changes in tonoplast proton pumps activity during elongation growth and was provided with tobacco suspension culture By-2 (wt and NAS lines).
