Abstract

Ammonium, the end-product of nitrate-reduction, causes a marked increase in nitrate-dependent formation of nitrate reductase activity in pea shoot apices. The ammonium effect is mediated via a decrease in the rate of nitrate reductase decay. The increased stability of the enzyme in the presence of ammonium is indirect and depends upon protein synthesis. A regulatory role for ammonium-induced protein(s) is suggested.
