Abstract
In Acer pseudoplatanus cells, the role of ATP and PPi in keeping the v acuolar Delta pH was investigated after treatments with 2-deoxy-D-gluc ose, inhibitor of glycolysis, and KCN, inhibitor of respiration, in or der to simulate a condition of glucose startvation and anoxia. It was concluded that the tonoplast H+-PPiase is responsible for the maintena nce of vacuolar Delta pH and that this enyme is the major consumer of PPi in metabolic inhibitor-treated cells.
