Acta Botanica Sinica, 2001•europepmc.orgEffect of nitrate and ammonium on the activity of tonoplast pyrophosphatase (V-PPase) was
investigated in the roots of tomato (Lycopersicon esculentum L.). The results showed that the
activity of V-PPase was increased by ammonium nutrition, compared with nitrate nutrition.
The H~(+) transport of tonoplast vesicles by V-PPase was also stimulated by ammonium
nutrition. The result of Western blot indicated that the protein amount of V-PPase was
increased by ammonium nutrition.
